Question

FIND THE VALUE OS COS(-1710)degree

Answer 1

send me a lot of question related to trigonometry

Answer 2

Answer:

The value of cos(-1710°) is 0

Step-by-step explanation:

Given the angle 1710°

We have to find the cos of angle i.e cos(1710°)

As we know cos(-x)=cos x

$\cos{-1710^{\circ}}=\cos{1710^{\circ}}=\cos({1710^{\circ}\times \frac{\pi}{180})}$

$=\cos{\frac{19\pi}{2}=\cos({9\frac{1}{2}\pi})$

$=\cos(10\pi-\frac{\pi}{2})$

$=\cos(-\frac{\pi}{2})$

$=\cos(-90)$

$=\cos(90)=0$

The value of cos(-1710°) is 0
