    Evaluating a definite integral....

    Evaluate:



    F(x) = \int_{x}^{6} \sin(t^{4}) dt


    I = ?

    I guess I is just the solution...

    As far as I can tell, you are only supposed toe valuate the integral, but I am not sure how to do that.

    I'm 99.45688% sure that integral doesn't exists as an expression with a finite number of elementary functions...Now, if it were that I = F'(x) then we do NOT need to know what the integral to solve the question...but we don't know what I is.

    Thank you for your help! For the...

    second part of the question I AM supposed to find F'(x).

    What are the steps involved in determining the derivative?
