Question

I’m having a lot of trouble with simplifying expressions with basic trigonometric identities

Answer 1

Given the following trigonometric expression:

$cos(\alpha)tan(\alpha)sec(\alpha)cot(\alpha)$

We will simplify the expression as follows:

First, we should know that: cot = 1/tan, and sec = 1/cos

So, the expression will be s follows:

$cos(\alpha)*tan(\alpha)*\frac{1}{cos(\alpha)}*\frac{1}{tan(\alpha)}$

Cross the similar terms.

So, the answer will be:

$1$
