# If $y = sin\theta$, then for what value of $\theta$, the relative error in y is minimum?

$90^0$

##### SOLUTION
$y=sin\theta$. . . . . . . . . . . . (1)
Differentiate with respect to $\theta$
$\dfrac{dy}{d\theta}=cos\theta$
For minimum , $\dfrac{dy}{d\theta}=0$
$cos\theta =0$
$\theta =90^0$
The correct option is A.

You're just one step away
