How to write the equation of a circle in polar form to rectangular

The video tutorial discusses solving a radius problem by identifying R-squared and cosine multiplication. The instructor explains why certain methods are not preferred and decides to square both sides to solve the problem. The session concludes with school and sports announcements.

What are the two methods mentioned for handling the variable R in equations?

• Identifying R as R-squared or multiplying by sine

• Identifying R as R-squared or multiplying by cosine

• Multiplying R by tangent or sine

• Squaring R or multiplying by tangent

Why is multiplying by cosine not preferred in the given context?

• It introduces an additional variable

• It makes the equation unsolvable

• It results in cosine appearing on both sides

• It complicates the equation by adding sine

What transformation occurs when R is multiplied by cosine?

• It becomes equal to Y

• It becomes equal to Z

• It becomes equal to X

• It becomes equal to W

What is the preferred method to handle the equation involving R?

• Multiply both sides by R

• Divide both sides by R

• Square both sides

• Multiply both sides by cosine
