Can sin and cos be the same

WebNotice in particular that sine and tangent are odd functions, being symmetric about the origin, while cosine is an even function, being symmetric about the y-axis. The fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions.

WebFor all θ θ in the domain of the sine and cosine functions, respectively, we can state the following: Since sin (− θ) = − sin θ, sin (− θ) = − sin θ, sine is an odd function. Since, cos (− θ) = cos θ, cos (− θ) = cos θ, cosine is an even function. The other even-odd identities follow from the even and odd nature of the ... WebJul 12, 2024 · Example 5.3.1.
