Given the following functions:
Find dy/dx.
Solution:
The first thing that we need to do is to get the derivative of the given functions with respect to their independent variables.
Take the derivative of the first equation with respect to u, we have
Take the derivative of the second equation with respect to u, we have
Since there are three variables in the given functions, then we have to use the Chain Rule in getting dy/dx, we have
Substitute the values of dy/du and dx/du to the above equation, we have
Since the two given equations have higher exponents and it's impossible to express each equations in terms of u, therefore
