Hint: In this problem, we have to find how sinx=0 equals π. We should always know that the sine value is always equal to zero for every multiple of π, where π radians is equal to 180. We can now draw a graph with a sine curve to see the value of sine for π.

Complete step by step answer:
We know that the given trigonometric function given is sine.
We should always remember that the sine value is always equal to zero for every multiple of π, where π radians is equal to 180.
We can now draw a graph with a sine curve to see the value of sine for π.

We can now see that the sine curve touches the line at 0 in every multiple of π.
We can now write it as,
sinx=0x=k×π
Where k is any whole number.
Therefore, we can summarize that every multiple of π for the sine function is always equal to zero.

Note: Students should also remember that π radians is equal to 180. We should also know that the sine function goes from 0 to 90=π2and then back to 0 to 180=π, and when we come down to -1 to 270=3π2 and when we go up to 0 again at 360=2π, therefore, it will be 0 at every multiple of π. We should also concentrate in the graph part while drawing the sine curve.
