Question

Which trigonometric function has the same value as sin 75?

Answer 1

The trigonometric function has the same value as $sin 75$ is $\cos 15$.

Step-by-step explanation:

We have,

$\sin 75$

To find, the trigonometric function has the same value as $sin 75$ = ?

$\sin 75$

= $\sin (90-15)$

Using the trigonometric identity,

$\cos A$  = $\sin (90-A)$

= $\cos 15$

∴ The trigonometric function has the same value as $sin 75$ = $\cos 15$

Thus, the trigonometric function has the same value as $sin 75$ is $\cos 15$.
