Spherical coordinates are expressed in the form [math]\left(\rho,\theta,\phi\right)[/math]. [br][br]For [math]\theta[/math] and [math]\phi[/math], this applet uses units of [b]RADIANS[/b]. Type "pi" if an angle is a multiple of [math]\pi[/math].[b][br][br][/b]Input the distance from the origin to the point, [math]\rho[/math], the angle measured from the positive x-axis, [math]\theta[/math], and the angle measured from the positive z-axis, [math]\phi[/math]. Then use the slider to watch the point as it is plotted. [b][br][br][/b]The[b][color=#ff7700] ORANGE [/color][/b]point is the point plotted in spherical coordinates.[br]For reference, you can toggle the "Show Sphere" on or off by checking the box.
