QUESTION:
Evaluate the trigonometric function using its period as an aid.
\(\sin 4 \pi\)
ANSWER:Step 1 of 2
A function is said to be periodic if \(f(t+c)=f(t)\), where c is any positive real number.
For the sine function the period is \(2 \pi\). Therefore
\(\sin (t+2 n \pi)=\sin t\) ................(1)
Here, n is any integer.
