Question

Y=tan^-1(a/x) + log √x-a/√x+a prove that dy/dx = 2a^3/x^4-a^4

Answer 1

In the attachment I have proved this problem.

The given function y is modified in such way that to make the differentiaion is simple.

After the differentiation , the derivative is simplified to get the result.

I hope this answer help you
