Question

Find the maximum value of the y-coordinate of the points on the limacon r=1+2cos(theta)

Answer 1

Might try converting to rectangular coordinates, then find dy/dx.

Answer 2

okay i'll give it a shot. this one has got me stumped.

Answer 3

Hint: solving for y will give you two functions; take the positive one since you're looking for a maximum.

Answer 4

Hmm, actually, might be better off using implicit differentiation than solving for y - might save a couple steps.

Answer 5

ok will do. thanks for the help
