Hint: In this problem, we have to find how equals . We should always know that the sine value is always equal to zero for every multiple of , where radians is equal to . We can now draw a graph with a sine curve to see the value of sine for .
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 , where radians is equal to .
We can now draw a graph with a sine curve to see the value of sine for .
We can now see that the sine curve touches the line at 0 in every multiple of .
We can now write it as,
Where k is any whole number.
Therefore, we can summarize that every multiple of for the sine function is always equal to zero.
Note: Students should also remember that radians is equal to . We should also know that the sine function goes from 0 to and then back to 0 to , and when we come down to -1 to and when we go up to 0 again at , therefore, it will be 0 at every multiple of . We should also concentrate in the graph part while drawing the sine curve.
