// input data
b = 40; // angle subtended by final images at eye in degrees
a = 10 // angle subtended by the object at the eye kept at near point in degrees
// Calculations
b_r = b*%pi/180; // degree to radian conversion
a_r = a*%pi/180; // degree to radian conversion
M = tan(b_r)/tan(a_r); // magnifying power
// Output
