Question

How do you convert `r = 5` into cartesian form?

Answer 1

`x^2+y^2=25`

Explanation:

To convert from `color(blue)"polar to cartesian form"`

`color(orange)"Reminder " color(red)(|bar(ul(color(white)(a/a)color(black)(r=sqrt(x^2+y^2))color(white)(a/a)|)))`

`r=5rArrsqrt(x^2+y^2)=5rArrx^2+y^2=25`

This is a circle, centred at the origin with radius of 5.
