Question

Which of the following is the co-function of cos 58 degrees?tan 58°sin 58°cos 32°sin 32°

Answer 1

`\sin 32^o`

Step-by-step explanation

We want to find the cofunction of the given function.

The cofunction of a cosine function is:

`\cos (\theta)=\sin (90-\theta)`

Therefore, the cofunction of cos(58) is:

`\begin{gathered} \cos (58)=\sin (90-58) \\ \cos (58^o)=\sin (32^o) \end{gathered}`

That is the answer.
