I need help differentiating these expressions. I'm taking Calc II right now so I'm reviewing the stuff I forgot how to do.

1.) e^{ln2x}

2.) sin6xcsc6x

3.) sin^{2}x/3 + cos^{2}x/3

3. The attempt at a solution

1.) This is 2. I know the ln cancels the power so it's simplified to 2x. What if the ln and e switched places? Would it still cancel out to 2x?

2.) I have no idea how to approach this problem. The answer is supposed to be 0. Do I use the product rule?

3.) I also don't know how to approach this problem. Are there any trig identities needed to know on how to solve this? The answer should be 0.
