# How to find the period of a trig function

This fundamental period of a function is also called the function period in which the function repeats itself. f(x +P) = f(x) f ( x + P) = f ( x) Note: the sine function is a periodic

## Finding the Period and Amplitude of a Sine Function

To find the period of any given trig function, first find the period of the base function. The period of sine, cosine, cosecant, and secant is 2 π. For tangent and cotangent, the period is π. Then
`

## Amplitude & period of sinusoidal functions from equation (video)

period formula for tangents & cotangents: \omega = \dfrac {\pi} {\lvert B \rvert} ω = ∣B∣π. In the sine wave graphed above, the value of the period multiplier B was 2. (Sometimes the value of B inside the function will be negative, which is why
