HI, I didn't study for my Trigonometry quiz and it's online so can anyone help me?
. I'm a senior so it's higher level trigonometry. The topics are as follows:
1.The cosecant, secant, and cotangent ratios
2. Compound angle formulae
3. Double angle formulae
4. Further trigonometric identities
5. Expressing asinθ+bcosθ in the form
R sin(θ ± α) or R cos(θ +− α)
