At what value of x is f(x) a minimum?   I know f'(x) = e^((x^2-3x)^2) , but I don't know how to continue.   Thanks!

## Trigonometric Substitution

Before I joined WyzAnt, I tutored an AP physics student who contacted me through the physics department. One day, he told me that his physics teacher didn't know how to solve a particular indefinite integral. I eventually wrote out a solution to the problem and used it to introduce the method of trigonometric substitution. Since WyzAnt doesn't support math markup in their blog entries, I will... read more
