Question

How do you create a cosine equation?

Answer 1

Definition of cosine equation :

The cosine function is also a sinusoidal function (like the sine function) that can be written as:

$y=A\cos (Bx+C)+D;A$ and $B$ is not equal to $0$. Where

$A$ is the amplitude .

$B$ is related to the period of one cycle equal by $2\pi /\left|B\right|$.

$C$ is the phase shift or horizontal shift.

$D$is the displacement or vertical shift.

If we consider, $C$and $D$ is equal to zero, then,

$Y=A\cos Bx$

Period $=2\pi /\left|B\right|$.
