Chapter 6: Q.42 (page 395)

$\sin θ, \cos θ$ are given .Find the exact value of each of the four remaining trigonometric functions $\sin θ = \frac{2 \sqrt{2}}{3}, \cos θ = - \frac{1}{3}$

Short Answer

Expert verified

The value of $c s c θ = \frac{3}{2 \sqrt{2}}, s e c θ = - \frac{1}{3}, \tan θ = - - 2 \sqrt{2}, c o t θ = - \frac{1}{2 \sqrt{2}}$

Step by step solution

Step 1. Given information

Here $\sin θ = \frac{2 \sqrt{2}}{3}, \cos θ = - \frac{1}{3}$ are given.

We need to find the exact value of each of the four remaining trigonometric functions

. Finding the value of trigonometric functions cscθ and secθ

In this question $\sin θ = \frac{2 \sqrt{2}}{3} s o c s c θ = \frac{1}{\sin θ} = \frac{1}{\frac{2 \sqrt{2}}{3}} = \frac{3}{2 \sqrt{2}} \cos θ = \frac{- 1}{3} t h e n s e c θ = \frac{1}{\cos θ} = \frac{1}{\frac{- 1}{3}} = - 3$

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

Here $\tan θ = \frac{\sin θ}{\cos θ} = \frac{\frac{2 \sqrt{2}}{3}}{- \frac{1}{3}} \sin c e \sin θ = \frac{2 \sqrt{2}}{3} a n d \cos θ = - \frac{1}{3} = - 2 \sqrt{2} a n d c o t θ = \frac{1}{\tan θ} = - \frac{1}{2 \sqrt{2}}$
