Question

I need help with this question. I just don’t understand it.

Answer 1

Answer:

The frequency of the sinusoidal wave is, $\frac{2}{\pi}$

Step-by-step explanation:

The frequency of a sine wave function states that the number of cycle it will completes in every second.

The formula for frequency:

$frequency = \frac{1}{Time period}$

From the given graph:

Time period = $\frac{\pi}{2}$

then;

$frequency = \frac{1}{\frac{\pi}{2}}=\frac{2}{\pi}$

Therefore, the frequency of the sinusoidal wave is, $\frac{2}{\pi}$
