Question

Information and formula on trignometry.
Any help will be apreciated.​

Answer 1

Identities:

• Cos² θ + Sin² θ = 1

• 1+Tan² θ = Sec² θ

• 1+Cot² θ = Cosec² θ

Complementary angles:

• sin(90°-θ)=cosθ

• cos(90°-θ)=sinθ

• tan(90°-θ)=cotθ

• cot(90°-θ)=tanθ

• sec(90°-θ)=cosecθ

• cosec(90°-θ)=secθ
