Today's assignment:
- Complete Exercises p. 333-335 #1-5, 10-13
If you want a proof of the sum identities you can find them here
Proof of sin(a+b)=cos(a)sin(b) + sin(a)cos(b)
Proof of cos(a+b)=cos(a)(cos(b) - sin(a)sin(b)
The proofs are done differently from the unit circle one I showed in class and may be clearer.
