Given:
x and y are both differentiable functions of t.
To find:
The value of .
Solution:
We have,
...(i)
At x=-1,
Divide both sides by 3.
Taking cube root on both sides.
So, y=2 at x=-1.
Differentiate (i) with respect to t.
Putting x=-1, y=2 and , we get
Divide both sides by -8.
Therefore, the value of is 36.
