Converting Spherical to Cartesian Coordinates

The video tutorial explains how to convert spherical coordinates to Cartesian coordinates. It begins with an introduction to the conversion process, followed by the formulas used for conversion. The tutorial then demonstrates how to use reference triangles to find trigonometric values, which are essential for the conversion. It includes detailed calculations of these values and concludes with a verification of the results using the unit circle.
