Expert Answer
Basis on the data, I think the question you have asked is:
Find dy/dx if 3x=t3 and 2y=t2
The above two equations are in parametric form which can be solved as follows:
Given: 3x=t3 and 2y=t2
Differentiating above equations w.r.t t, we get
3 dx/dt = 3t2 and 2 dy/dt = 2t
dx/dt = t2 ... (i) and dy/dt = t ... (ii)
Dividing (ii) by (i), we get
(dy/dt)/(dx/dt) = t/t2
Hence, dy/dx = 1/t
