More Derivation Rules

I hope everyone knew (and still know) rules for Trig Functions, because we took a quiz on the last week or so today, and if you didn't you missed a good 30-40% of the problems. Whoops. Anyway, we continued Rules today with Inverse Trig Functions and Logarithms/Exponential Functions. They are as follows:
Inverse Trig Functions:
Logarithms/Exponential Functions:
On that note:
Marchetti in 9 Months:
A mathematician went insane and believed that he was the differentiation operator. His friends had him placed in a mental hospital until he got better. All day he would go around frightening the other patients by staring at them and saying "I differentiate you!"
One day he met a new patient; and true to form he stared at him and said "I differentiate you!", but for once, his victim's expression didn't change.
Surprised, the mathematician marshalled his energies, stared fiercely at the new patient and said loudly "I differentiate you!", but still the other man had no reaction. Finally, in frustration, the mathematician screamed out "I DIFFERENTIATE YOU!"
The new patient calmly looked up and said, "You can differentiate me all you like: I'm e to the x."

I didn't want to draw a picture. Sorry.
