How to convert a rectangular coordinate to polar

The video tutorial explains how to convert X&Y coordinates to polar coordinates. It covers graphing points, calculating the radius using the Pythagorean theorem, and determining the angle Theta using tangent and the unit circle. The tutorial emphasizes understanding the relationship between the opposite and adjacent sides in a right triangle and how these relate to polar coordinates.

What is the primary focus when converting Cartesian coordinates to polar coordinates?

• Finding the midpoint

• Calculating the slope

• Determining the radius and angle

• Identifying the intercepts

How is the radius (R) calculated for the point (1, 1) in polar coordinates?

• R = 1 * 1

• R = sqrt(1^2 + 1^2)

• R = 1 + 1

• R = 1 / 1

What is the value of R for the point (1, 1) after calculation?

• 2

• 1

• 3

• sqrt(2)

Which trigonometric function is used to find the angle Theta in polar coordinates?

• Cotangent

• Sine

• Cosine

• Tangent

What is the angle Theta for the point (1, 1) in polar coordinates?

• π

• π/4

• π/2

• 3π/2
