Answer 2

$\displaystyle \sf{ } \: \lim_{x \to \frac{\pi}{4} } \: \sin 2x = 1$

Given :

$\displaystyle \sf{ } \: \lim_{x \to \frac{\pi}{4} } \: \sin 2x$

To find :

The value of limit

Solution :

Step 1 of 2 :

Write down the given limit

Here the given limit is

$\displaystyle \sf{ } \: \lim_{x \to \frac{\pi}{4} } \: \sin 2x$

Step 2 of 2 :

Find the value

$\displaystyle \sf{ } \: \lim_{x \to \frac{\pi}{4} } \: \sin 2x$

$\displaystyle \sf{ } \: = \sin \frac{2\pi}{4}$

$\displaystyle \sf{ } \: = \sin \frac{\pi}{2}$

$\displaystyle \sf{ } \: = 1$
