# Math Help - Differentiation - parametric form

1. ## Differentiation - parametric form

x=(sin^3)t/(sqrt(cos2t) and y=(cos^)3t/(sqrt(cos2t)

y=(cot^3)t *x

after that what should be donr

2. Personally, I would start with an actual problem statement. Are we converting to Cartesian Coordinates?

3. we have to find dy/dx

You do not need to convert just take the derivatives and use the above.

5. By the way, there is no such thing as (sin^3)t or (cos^3)t. You mean sin^3(t) and cos^3(t).
