The values for the function y= cos 4(x-pi) are;
- Amplitude = 1
- Period = π/2
- Horizontal (phase) shift = π
- units Vertical shift = 0 units
Cosine functions and Properties
It follows from comparison with the traditional cosine function;
- Amplitude is usually the coefficient of the cos function and hence is, 1 in this case.
- The period, T from the function given is; T =π/2
- The horizontal phase shift is obtained by comparison as; pi.
- Ultimately, the vertical shift is 0 units as there's no y-intercept.
