# Problems on proving given functions again

I really need help on this.

Show that each of the following functions satisfy the given relative function that includes partial differentiation.

Show that each of the following functions satisfy the given relative function that includes partial differentiation.

1. differentiate z w.r.t x and then w.r t. y and compare f'(ax+by)... you will get the ans.

2. differentiate z w.r.t x and then w.r t. y and then compare then solve for LHS and whenever there is x^n*f(y/x), substitute z for it.

Thanks,I have solved it 😀Sagar071. differentiate z w.r.t x and then w.r t. y and compare f'(ax+by)... you will get the ans.
