Cosine Of 2pi
Cosine Of 2piTo write a sine function you simply need to use the following equation: f(x) = asin(bx + c) + d, where a is the amplitude, b is the period (you can find the period by dividing the absolute value b by 2pi; in your case, I believe the frequency and period are the same), c is the phase shift (or the shift along the x-axis), and d is the vertical. This is because we get an error when we solve on a calculator, since the domain of the inverse cosine function is.
