# How to find the amplitude period and frequency of a trigonometric function?

Amplitude and frequency are two important characteristics of periodic and repeating functions.

## Answer: The amplitude and frequency of the function asin (bx) will be a and b/2 π

Trigonometric functions are generally employed in calculations of amplitude and frequency due to their periodic nature.

**Explanation:**

Amplitude = 1/2[ (Highest value) - (Lowest value)]

Frequency is the number of occurrences of a repeating event per unit of time.

Frequency = 1/Period

For ex, f(x) = asin (bx)

amplitude = a

frequency = b/2 π
