It is best to vectorize your function using element-wise operations, then create it as a function of the two variables, then use integral2 to numerically integrate it: m = 3; n = 5; p = 7; f = @(theta,phi) m*p*cos(theta).^3.*sin(phi).^2 - n*p*cos(phi).^2.*cos(theta...
To find the sine of 15 degrees, we can draw a right triangle with one of the angles as 15 degrees. Using basic trigonometric ratios, sine theta = opposite side/hypotenuse. For a 15 degree angle, the opposite side will be 0.2588 and hypotenuse will be 1. So, sin 15 = 0.2588. What...
