How do you convert polar coordinates to rectangular coordinates?
(r, (theta) )
X=rCos(theta) Y=rSin(theta)
How do you convert rectangular coordinates to polar coordinates?
(x, y)
x^2+y^2=r^2 tan(theta)= y/x
How do you convert the equation to rectangular form?
r=5
x^2+y^2=25

r=8Sin(theta)
r^2=8rSin(theta)
x^2+y^2=8y

4sin(theta)-6cos(theta)=r
4y+6x=x^2+y^2
What does rSin(theta) equal?
Y
What does rCos(theta) equal?
X
