Question

Given r = cos theta, is the answer x^2 +y^2 =x in rectangular format?

Mathway doesn't understand conversions.

Answer 1

`"yes"`

Explanation:

`"using the "color(blue)"conversions"`

`•color(white)(x)r=xcosthetarArrcostheta=x/r`

`•color(white)(x)r=sqrt(x^2+y^2)rArrr^2=x^2+y^2`

`rArrr=x/r`

`rArrr^2=x`

`rArrx^2+y^2=x`
