    Is this a valid operation?

    Hi everyone,
    I need get the integral of the following expression and I tried to do it the following way. Is this a valid operation?
    Any help will be highly appreciated?

    Thanks

    That's weird. The original integral is dz (i.e., we're integrating wrt z), yet z itself appears as upper limit: how's this possible?

    I am sorry Tonio,
    That was a typo, Its suppose to be the upper case Z. But I was wondering, it I could use such chain rule and get the dh/dt and dz/dt out of the integral like that.
    Then I have a predefined function of which is x = (1+(ba)^n)^-(1+1/n). So. Now I can differentiate this function w.r.t. a, and then integrate within the limit of (0 to Z).
    Is this mathematically legitimate?. I would be grateful If I could get some help in solving this.

    Thanks

    If h and z are functions of a then they cannot be taken outside the integral.

    Actually they are not function of a. does that allow me to do this operation? And following that, I have to differentiate x wrt a and then integrate it? Can that be done?
