Find dy/dx and d2y/dx2 by implicit differentiation for:


Solution:

Consider the given equation above


Take the first derivative of the given equation with respect to x by implicit differentiation, we have 








Finally, take the second derivative of the above equation with respect to x by implicit differentiation, we have 










but


Hence, the above equation becomes






 

We can further simplify the above equation by using the given equation as follows  


Therefore,
