In 3D space, the Cartesian coordinates (x, y, z) can be converted to spherical coordinates (r:radius, 8:inclination, :azimuth) by the following equations: r = + y+2, 0= cos() -tan (#) Write a program in a script file named 'pracscript' to receive Cartesian coordinates from user's input, and call a function named 'printspherical' that prints the spherical coordinates. The function printspherical calls a subfunction convert2spher that converts from Cartesian to spherical coordinates. (Hint:MATLAB function acos(x) returns the inverse Cosine (cos) of a, atan(x) returns the inverse Tangent (tan) of a).
