Pre calculus question: Type the correct answer in each box. If necessary, use A to represent the angle. Complete the statements.

1. X^2+y^2=y is written in polar form as r= *BLANK*

2. r=3sinA is written in rectangular form x^2+y^2= *BLANK*

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
