# Math Assignment Help With Trigonometric Functions

## 9.3 Trigonometric functions:

i) SinA = Perpendicular = b

Hypotenuse c

ii) CosA = Base = a

Hypotenuse c

iii) TanA = Perpendicular = b

Base a

iv) CosecA= Hypotenuse = c

Perpendicular b

v) SecA = Hypotenuse = c

Base a

vi) CotA = Base = a

Perpendicular b

Points To Remember:

For any angle θ

Cosecθ = 1 / Sinθ

Secθ = 1/ Cosθ

Cotθ = 1/Tanθ
