Homework Help: Calculus

Posted by Joshua on Friday, March 13, 2009 at 2:20pm.

I wanted to confirm that I solved these problems correctly (we had to convert the polar curves to Cartesian equations).

1.rcos(theta)=1
x=1
2.r=2*sin(theta)+2*cos(theta)
r^2=2rsin(theta)+2rcos(theta)
x^2+y^2=2y+2x (a little unsure what do next if this is correct)
3.r=tan(theta)sec(theta)
r=sin(theta)/(cos(theta))^2
r(cos(theta))^2=sin(theta)
r^2(cos(theta))^2=rsin(theta)
x^2=y
