You have two angles in spherical coordinates; [math]\theta[/math] and [math]\varphi[/math] which [math]\theta[/math] is the positive angle starting from x axis, on xy plane and [math]\varphi[/math] is the positive angle starting from z axis.[br][br]This applet includes two angle options for both angle types. You can set the angles to create an interval which you would like to see the surface.[br][br]Additionally, spherical coordinates includes a distance called [math]\rho[/math] starting from origin. This distance depend on [math]\theta[/math] and [math]\varphi[/math]. You will write a two variable function for [math]\rho[/math] using x and y for [math]\theta[/math] and [math]\varphi[/math] respectively.[br][br]Review the spherical coordinates by using below applet[br][br]For further quetions tolgakabaca@gmail.com.[br][br]Dr Tolga KABACA[br]
