I am a senior in high school, and I'm having some trouble solving these HW problems.

I would appreciate your help. It would be better if you game me the solutions and how to get there, too. Thank you.

Write each expression in terms of sine and cosine, and simplify so that no quotients appear in the final expression.

1.- -tan x cos x

2.- cot**Θ **sin**Θ**

3.- cos**Θ **csc**Θ**

4.- (1-cosΘ) (1+secΘ)

5.- sinΘ(cscΘ-sinΘ)
