Writing a vertical line in polar form

The video tutorial introduces rectangular equations and their graphing on an XY axis. It then transitions to explaining how to convert these equations into polar coordinates using R and Theta. The tutorial further simplifies polar equations by dividing by cosine of Theta and discusses trigonometric identities, such as secant, to aid in understanding these conversions.

What are rectangular equations typically expressed in terms of?

• A and B

• X and Y

• R and Theta

• M and N

When converting to polar form, what does X become?

• Y

• R Cosine of Theta

• Theta

• R

What operation is performed to solve for R in polar equations?

• Subtract sine of Theta

• Multiply by sine of Theta

• Add cosine of Theta

• Divide by cosine of Theta

What is another way to express 1 over cosine of Theta?

• Sine

• Tangent

• Cotangent

• Secant

Which trigonometric identity is used in simplifying polar equations?

• Tangent equals sine over cosine

• Cosine equals adjacent over hypotenuse

• Sine equals opposite over hypotenuse

• Secant equals 1 over cosine
