Chapter 6: Q. 36 (page 395)

$\sin θ, \cos θ$ are given. Find the exact value of each of the four remaining trigonometric functions. $\sin θ = \frac{4}{5}, \cos θ = - \frac{3}{5}$

Short Answer

Expert verified

The value of $c s c θ = \frac{5}{4}, s e c θ = - \frac{5}{3}, \tan θ = \frac{- 4}{3} a n d c o t θ = - \frac{3}{4}$

Step by step solution

Step 1. Given information

Here $\sin θ = \frac{4}{5} a n d \cos θ = - \frac{3}{5}$ are given.

We have to find out the exact value of each of the four remaining trigonometric functions.

. Finding the value of trigonometric functions cscθ,secθ

Here

$\sin θ = \frac{4}{5} s o c s c θ = \frac{1}{\sin θ} = \frac{1}{\frac{4}{5}} = \frac{5}{4} \cos θ = \frac{- 3}{5} t h e n s e c θ = \frac{1}{\cos θ} = \frac{1}{\frac{- 3}{5}} = - \frac{5}{3}$

Step 3.. Finding the value of trigonometric function tanθ,cotθ

We know that $\tan θ = \frac{\sin θ}{\cos θ} = \frac{\frac{4}{5}}{\frac{- 3}{5}} \sin c e \sin θ = \frac{4}{5} a n d \cos θ = \frac{- 3}{5} = \frac{- 4}{3} a n d c o t θ = \frac{1}{\tan θ} = \frac{1}{\frac{- 4}{3}} = \frac{- 3}{4}$
