The period of y=5 cos pi x is 2 but I don't know how to find it.
Doesn't the cosine function repeat each 2PI radians? So when X=2, or 4, or 2*whole number, it repeats.
Thanks. I think I got it
To find the period of the function y=5cos(πx), you can use the formula:
Period = 2π / |B|
In this case, the coefficient for x is π, so B = π.
Applying the formula, we have:
Period = 2π / |π| = 2π / π = 2
Therefore, the period of the function y=5cos(πx) is 2.
