Learn to convert rectangular coordinates to polar form

The video tutorial explains how to convert Cartesian coordinates to polar form. It begins by introducing the problem and the need to find both the distance and the angle. The distance is calculated using the Pythagorean theorem, resulting in a value of 5. The angle is determined using the inverse tangent function, yielding 53.1 degrees. The final polar coordinate is presented as (5, 53.1 degrees).

Explain the significance of the Pythagorean theorem in this context.
