# Write the Range of the Function F(X) = Sin X, Where − π 4 ≤ X ≤ π 4 . - Mathematics

Sum

Write the range of the function f(x) = sin [x], where $\frac{- \pi}{4} \leq x \leq \frac{\pi}{4}$ .

#### Solution

Given : f(x) = sin [x], where $\frac{- \pi}{4} \leq x \leq \frac{\pi}{4}$ $- \frac{\pi}{4} \leq x \leq \frac{\pi}{4}$
$\Rightarrow - 0 .785 \leq x \leq 0 . 785$
$\therefore x \in \left[ - 0.785, 0.785 \right]$
$\text{ Or } x = {0, 1}$
$\text{ Thus, range of } f(x) = \sin [x] \text{ is }$
{ sin (-1), sin(0) ,  sin (1) } .
