Question

convert r^2=cos(theta) to rectangular coordinates

Answer 1

I basicly multiply r on both sides. Which in turn it will be r*r^2=cos(theta) r
In which cos(theta) r is "x"

r*r^2=x
And r^2 is x^2+y^2
And r is root(x^2+y^2)

root(x^2+y^2)*x^2+y^2=x
root(x^2+y^2)*x^2+y^2—x=0
I need to simplify? If i do can you help.

Answer 2

I know the exponent for (x^2 +y^2) is 3/2 but why

Answer 3

Nvm I found out why. Thanks useless people :D

Answer 4

Just add exponents 1/2+1= 3/2
