convert from polar form into rectangular form. type the equation in rectangular form (simplified):

1) rsecθ = 3

2) r=5/cosθ-2sinθ

3) r=5cscθ

we know r^2 = x^2 + y^2 and x/r =cosØ, y/r = sinØ

given:

rsecØ = 3

r = 3/secØ

r = 3cosØ

r = 3(x/r)

r^2 = 3x

x^2 + y^2 = 3x , rewrite it any way you want.

the last one is done the same way

2nd :

I will assume you r = 5/(cosØ-2sinØ

r = 5/(x/r - 2y/r)

r = 5/((x-2y)/r)

r = 5 * r/(x - 2y)

1 = 5/(x-2y)

x-2y = 5
