How do you evaluate $\arcsin (0)$ without a calculator?

Hint: The arcsine is the inverse of the trigonometric representation of sine. The range of arcsine is from negative of $\dfrac{\pi }{2}$ to positive of $\dfrac{\pi }{2}$. The domain of arcsin is from negative 1 to positive 1. It is a bijective function, which means it will be invertible. This property will be very useful in this question.

Complete step by step solution:
According to the question, we have to find the value of ${\sin ^{ - 1}}(0)$,
So, let ${\sin ^{ - 1}}(0)$=x
Now,
Let us draw a triangle with $\sin x$= $0$
In this right-angled triangle,

We have considered the angle between base and Hypotenuse as x.
The angle between the base and the height = $90 ^{\circ}$
Now taking sine function both sides we will get,
$\sin ({\sin ^{ - 1}}(0)) = \sin (x)$
And as we know that $\sin ({\sin ^{ - 1}}\theta ) = \theta $, if$\theta $ is from negative one to positive one, so in the equation $\theta = (0)$
Hence, the equation changes to $\sin (x) = 0$
So, as we know the value of $\sin \theta $ for different values of $\theta $, we know that when $\theta = 0$ or $\theta = \pi $ $\sin \theta $ will give the value $0$.
Hence now we know that for getting a result equal to zero, we must give input as $\theta = 0$ or $\theta = \pi $
But, the range of arcsine is from $ - \dfrac{\pi }{2}$ to $\dfrac{\pi }{2}$, but only one result in inside this range, that is $\theta = 0$, but $\theta = \pi $ is outside the range, so it will not be considered.

So, our answer is $x = 0$.

Note:
The arcsine is the inverse of a tan trigonometric function. It is a bijective function, that is, it gives a unique value of every unique input and for every output one single input is considered. Bijective also means it is invertible, that is why we changed arsine to sin easily in our solution. This property is valid only for its respective domain, which is from a negative one to a positive one.
