Use the Intermediate Value Theorem to prove that the equation sin x = 2 cos2 x + 0.5 has at least one solution. 9. Prove the quotient rule (Theorem 3.2.11 on section 3.2 in the textbook). You can do two different proofs: (a) Do a proof assuming both the Product Rule (Theorem 3.2.6) and the Reciprocal Rule (Theorem 3.2.9). (b) Do a direct proof using only the definition of derivative as a limit. (Look at the proof of Theorem 3.2.6 as inspiration.)...
