Write a Matlab function called spher2cart that will convert Spherical coordinates to Cartesian coordinates. Note that this function will have three inputs and three outputs. Test you function using spherical coordinates: rho, theta, Phi) = (2, 3/4 pi, 3/4 pi). For this program, once it works, add the margin commands to check for correct number of inputs and write appropriate messages. Converting from spherical to Cartesian coordinates Notice that, by the Pythagorean Theorem S = Squareroot x^2 +^2 = rho sin Phi rho = squareroot S^2 + z^2 = squareroot x^2 + y^2 + z^2 x = S cos theta = rho sin phi cos theta y = S sin theta - rho sin phi sin theta z = rho cos phi
