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

Solution:

Amplitude and frequency are two important characteristics of periodic and repeating functions. Trigonometric functions are generally employed in calculations of amplitude and frequency due to their periodic nature.

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

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

Frequency = 1/Period

Sine wave curve

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

amplitude = a

frequency = b/2 π 

Thus, the amplitude and frequency of the function asin (bx) will be a and b/2 π
