Answer these simple questions and solve the problem yourself.

1)What do you intend to find?Write down an expression for it.

2)I am listing a few things. Tell whether you can find their value, if yes, what is their value:

S

a

V

dS/dt

da/dt

dS/da

dV/da

dS/dV

dV/dS

3)Write an expression for dV/dt. What values do you need for it?Can you find those values in ques.2?

I hope that you can solve the problem now. I still you have any problem, post it and i will try to tell you, straightaway this time.

To find dy/dx . There are two cases(for explicit functions):you want to find dy/dx in terms or yuo want to find dy/dx in terms of y.

To find in terms of x, express y as a function of x and differentiate.

to find in terms of y, express x as a function of y and differentiate.

Keep Smiling
