+Symbolics with Sage
+-------------------
+
+Hello friends and welcome to the tutorial on Symbolics with Sage.
+
+{{{ Show welcome slide }}}
+
+During the course of the tutorial we will learn
+
+{{{ Show outline slide  }}}
+
+* Defining symbolic expressions in Sage.  
+* Using built-in constants and functions. 
+* Performing Integration, differentiation using Sage. 
+* Defining matrices. 
+* Defining symbolic functions.  
+* Simplifying and solving symbolic expressions and functions.
+
+In addtion to a lot of other things, Sage can do Symbolic Math and we shall
+start with defining symbolic expressions in Sage. 
+
+Have your Sage notebook opened. If not, pause the video and
+start you Sage notebook right now. 
+
+On the sage notebook type::
+   
+    sin(y)
+
+It raises a name error saying that ``y`` is not defined. We need to
+declare ``y`` as a symbol. We do it using the ``var`` function. 
+::
+
+    var('y')
+   
+Now if you type::
+
+    sin(y)
+
+Sage simply returns the expression.
+
+Sage treats ``sin(y)`` as a symbolic expression. We can use this to do
+symbolic math using Sage's built-in constants and expressions.
+
+Let us try out a few examples. ::
+   
+   var('x,alpha,y,beta') 
+   x^2/alpha^2+y^2/beta^2
+
+We have defined 4 variables, ``x``, ``y``, ``alpha`` and ``beta`` and
+have defined a symbolic expression using them.
+ 
+Here is an expression in ``theta``  ::
+   
+   var('theta')
+   sin(theta)*sin(theta)+cos(theta)*cos(theta)
+
+Now that you know how to define symbolic expressions in Sage, here is
+an exercise. 
+
+{{ show slide showing question 1 }}
+
+%% %% Define following expressions as symbolic expressions in Sage. 
+   
+   1. x^2+y^2
+   #. y^2-4ax
+  
+Please, pause the video here. Do the exercise and then continue. 
+
+The solution is on your screen.
+
+{{ show slide showing solution 1 }}
+
+Sage also provides built-in constants which are commonly used in
+mathematics, for instance pi, e, infinity. The function ``n`` gives
+the numerical values of all these constants.
+:: 
+    n(pi) 
+    n(e) 
+    n(oo)
+   
+If you look into the documentation of function ``n`` by doing
+
+::
+   n(<Tab>
+
+You will see what all arguments it takes and what it returns. It will
+be very helpful if you look at the documentation of all functions
+introduced in the course of this script.
+
+Also we can define the number of digits we wish to have in the
+constants. For this we have to pass an argument -- digits.  Type
+
+::
+
+   n(pi, digits = 10)
+
+Apart from the constants Sage also has a lot of built-in functions
+like ``sin``, ``cos``, ``log``, ``factorial``, ``gamma``, ``exp``,
+``arcsin`` etc ...
+
+Lets try some of them out on the Sage notebook.
+::
+     
+   sin(pi/2)
+   
+   arctan(oo)
+     
+   log(e,e)
+
+Following are exercises that you must do. 
+
+{{ show slide showing question 2 }}
+
+%% %% Find the values of the following constants upto 6 digits
+      precision
+   
+   1. pi^2
+   #. euler_gamma^2
+
+
+%% %% Find the value of the following.
+
+   1. sin(pi/4)
+   #. ln(23)  
+
+Please, pause the video here. Do the exercises and then continue.
+
+The solutions are on your screen
+
+{{ show slide showing solution 2 }}
+
+Given that we have defined variables like x, y etc., we can define an
+arbitrary function with desired name in the following way.::
+
+       var('x') 
+       function('f',x)
+
+Here f is the name of the function and x is the independent variable .
+Now we can define f(x) to be ::
+
+     f(x) = x/2 + sin(x)
+
+Evaluating this function f for the value x=pi returns pi/2.::
+	   
+	   f(pi)
+
+We can also define functions that are not continuous but defined
+piecewise.  Let us define a function which is a parabola between 0
+to 1 and a constant from 1 to 2 .  Type the following 
+::
+      
+
+      var('x') 
+      h(x)=x^2 
+      g(x)=1 
+
+      f=Piecewise([[(0,1),h(x)],[(1,2),g(x)]],x) 
+      f
+
+We can also define functions convergent series and other series. 
+
+We first define a function f(n) in the way discussed above.::
+
+   var('n') 
+   function('f', n)
+
+
+To sum the function for a range of discrete values of n, we use the
+sage function sum.
+
+For a convergent series , f(n)=1/n^2 we can say ::
+   
+   var('n') 
+   function('f', n)
+   f(n) = 1/n^2
+   sum(f(n), n, 1, oo)
+
+ 
+Lets us now try another series ::
+
+
+    f(n) = (-1)^(n-1)*1/(2*n - 1)
+    sum(f(n), n, 1, oo)
+
+This series converges to pi/4. 
+
+Following  are exercises that you must do. 
+
+{{ show slide showing question 3 }}
+
+%% %% Define the piecewise function. 
+   f(x)=3x+2 
+   when x is in the closed interval 0 to 4.
+   f(x)=4x^2
+   between 4 to 6. 
+   
+%% %% Sum  of 1/(n^2-1) where n ranges from 1 to infinity. 
+
+Please, pause the video here. Do the exercise(s) and then continue. 
+
+{{ show slide showing solution 3 }}
+
+Moving on let us see how to perform simple calculus operations using Sage
+
+For example lets try an expression first ::
+
+    diff(x**2+sin(x),x) 
+
+The diff function differentiates an expression or a function. It's
+first argument is expression or function and second argument is the
+independent variable.
+
+We have already tried an expression now lets try a function ::
+
+   f=exp(x^2)+arcsin(x) 
+   diff(f(x),x)
+
+To get a higher order differential we need to add an extra third argument
+for order ::
+ 
+   diff(f(x),x,3)
+
+in this case it is 3.
+
+Just like differentiation of expression you can also integrate them ::
+
+     x = var('x') 
+     s = integral(1/(1 + (tan(x))**2),x) 
+     s
+
+Many a times we need to find factors of an expression, we can use the
+"factor" function
+
+::
+
+    y = (x^100 - x^70)*(cos(x)^2 + cos(x)^2*tan(x)^2) 
+    f = factor(y)
+
+One can simplify complicated expression ::
+    
+    f.simplify_full()
+
+This simplifies the expression fully. We can also do simplification of
+just the algebraic part and the trigonometric part ::
+
+    f.simplify_exp() 
+    f.simplify_trig()
+    
+One can also find roots of an equation by using ``find_root`` function::
+
+    phi = var('phi') 
+    find_root(cos(phi)==sin(phi),0,pi/2)
+
+Let's substitute this solution into the equation and see we were
+correct ::
+
+     var('phi') 
+     f(phi)=cos(phi)-sin(phi)
+     root=find_root(f(phi)==0,0,pi/2) 
+     f.substitute(phi=root)
+
+as we can see when we substitute the value the answer is almost = 0 showing 
+the solution we got was correct.
+
+Following are a few exercises that you must do. 
+
+%% %% Differentiate the following. 
+      
+      1. sin(x^3)+log(3x)  , degree=2
+      #. x^5*log(x^7)      , degree=4 
+
+%% %% Integrate the given expression 
+      
+      sin(x^2)+exp(x^3) 
+
+%% %% Find x
+      cos(x^2)-log(x)=0
+      Does the equation have a root between 1,2. 
+
+Please, pause the video here. Do the exercises and then continue. 
+
+
+Lets us now try some matrix algebra symbolically ::
+
+   var('a,b,c,d') 
+   A=matrix([[a,1,0],[0,b,0],[0,c,d]]) 
+   A
+
+Now lets do some of the matrix operations on this matrix
+::
+    A.det() 
+    A.inverse()
+
+
+Following is an (are) exercise(s) that you must do. 
+
+%% %% Find the determinant and inverse of :
+
+      A=[[x,0,1][y,1,0][z,0,y]]
+
+Please, pause the video here. Do the exercise(s) and then continue. 
+
+
+{{{ Show the summary slide }}}
+
+That brings us to the end of this tutorial. In this tutorial we learnt
+how to
+
+* define symbolic expression and functions
+* use built-in constants and functions  
+* use <Tab> to see the documentation of a function
