This is a graded discussion: 100 points possible due Feb 24 Antiderivatives we can't Compute At 5 5 Think back through the quarter and how many different kinds of functions for which we were able to compute an antiderivative. We've used "derivatives in reverse," substitution rule, integration by parts, trigonometric substitution, and partial fractions. Even with all of those techniques, there are still functions for which we (being mathematicians in general) are unable to compute. For this participation forum, I'd like you to come up with a function for which we cannot find an antiderivative expression, regardless of which antiderivative techniques or "algebraic tricks" we use. Post that indefinite integral expression as your reply (complete with integral symbol and differential). Your answer should look something like this... (your function here)dr
