Question
To get points for this, please complete all parts to the problem. Bonus points: Write it down on paper and take a picture of it showing all of your steps. Please prove your work completely. If it is completed entirely with good explinations, and work, you will get the points. I really need to understand this so it would be very helpful if you show all steps. I'm not expecting it to be answered in 4 hours. If you're working on it, please post here, and I'll gladly wait longer.

Explanation / Answer
(a) tan (a + b) = [ tan(a) + tan(b) ] / [ 1 - tan(a)tan(b) ]
LHS = sin(a + b) / cos(a + b) = [sin(a)cos(b) + cos(a)sin(b)] / [cos(a)cos(b) - sin(a)sin(b)]
Divide Numerator and Denominator by cos(a)cos(b) ......
= [ tan(a) + tan(b) ] / [ 1 - tan(a)tan(b) ] = RHS ...
Rest coming soon ...
