This chapter is where I'll put some of the problem types that I don't know what to do with because they're difficult and less-common.
Derivatives with Variables In Both Exponent & Base
This video covers an unusual type of derivative (possibly called "logarithmic differentiation") where X is raised to the power of itself, so the power rule doesn't apply: xx and (sinX)x. If your teacher covers this, you'll need to memorize the steps I present here, because you'll never figure out the trick on these otherwise!
If you do not have an account, you should get one, because it is awesome! You can save a playlist for each test or each chapter, and save your "greatest hits" into a "watch right before the final" list (not that we recommend cramming, but when in Rome...)
