Question

Evaluate the six trigonometric functions of the angle 0

Answer 1

# Sin θ = 9/15.

# Cos θ = 12/15.

# Cosec θ = 15/9.

# Sec θ = 5/4

Step-by-step explanation:

`by \: using \: pythagorian \: triplets`

`{a}^(2) + {b}^(2) = {c}^(2)`

`{9}^(2) + {12}^(2) = {c}^(2)`

`81 + 144 = {c}^(2)`

`225 = {c}^(2)`

`c = 15.`

`\sin θ = (9)/(15)`

`\cos θ = (12)/(15) = (4)/(5)`

`\csc θ = (15)/(9)`

`\secθ = (5)/(4)`
