Question: Do you know any antiderivative that maple can't find but we can?

I need to find an example of a function of one variable that has an antiderivative that can be expressed very simply in terms of fuctions that a 1st-year calculus student would know, but int (command name in maple) can't find an antiderivative.

Hint: Start with the antiderivative F(x), and get f(x) by differentiating it and simplifying. You might try something involving a few square roots and logarithms or exponentials or trigonometric functions.

I've spent more than 2 days to solve this question, but still in trouble. Please somebody help me! Thank you in advance!
