Converting Points from rectangular form to polar form

The video tutorial explains how to convert rectangular coordinates to polar form. It covers plotting points, calculating the length R using the formula r^2 = x^2 + y^2, and finding the angle Theta using tangent and inverse functions. The tutorial also discusses how calculators compute angles in different quadrants and concludes with converting the coordinates to polar form and radians.

What are the two main components we need to find when converting rectangular coordinates to polar coordinates?

• Height and Base

• Length and Width

• Radius and Diameter

• Length and Angle

Which formula is used to calculate the length R in polar coordinates?

• R^2 = X^2 + Y^2

• R = X + Y

• R = X - Y

• R = X * Y
