//Example 1.20
//To find values of all trigonometric values of given angle of 120
theta=120; //given angle in degree
//Consider a point (-1,sqrt(3)) in 2nd quadrant
//This point can be used on terminal side of 120
//Thus for a basic right angled triangle formed in second quadrant
adjacent = 1;
opposite = sqrt(3);
//by pythagoras theorem
hypotenuse = sqrt(adjacent^2 + opposite^2);
//since its third quadrant
