Question

How is cosine calculated?

Answer 1

The cosine of an angle is described as the length of the adjacent side $\left(A\right)$ divided by length of the hypotenuse $\left(H\right)$.

it is written simply as '$\cos$'.

$cosx=\frac{\mathrm{A}}{\mathrm{H}}$

Hence, we can calculate $\mathit{c}\mathit{o}\mathit{s}$ by the formula $\frac{\mathbf{B}\mathbf{a}\mathbf{s}\mathbf{e}}{\mathbf{h}\mathbf{y}\mathbf{p}\mathbf{o}\mathbf{t}\mathbf{e}\mathbf{n}\mathbf{u}\mathbf{s}\mathbf{e}}$
