Short Answer

Expert verified

We have proved the identitysec胃+tan胃cot胃+cos胃=tan胃sec胃.

Step by step solution

01

Step 1. Given information.

We have:

sec胃+tan胃cot胃+cos胃=tan胃sec胃

02

Step 2. Establish the identity.

Take the left hand side:

sec胃+tan胃cot胃+cos胃=1cos胃+sin胃cos胃cos胃sin胃+cos胃=1+sin胃cos胃cos胃+sin胃cos胃sin胃=1+sin胃cos胃脳sin胃cos胃+sin胃cos胃=1+sin胃cos胃脳sin胃cos胃1+sin胃=1cos胃脳sin胃cos胃=tan胃sec胃

Hence, proved.
