Question

Simplify 3(tan ^2 0 - sec^2?0)

Answer 1

Explanation:

answer is -3 because tan^2 theta-sec^2 theta means -1 and when u multiply -1 and 3 u will get -3.

Answer 2

A trigonometric expression is given to us and we need to simplify it and find out the value.

Given Expression :-

`\sf\implies 3(tan^2\theta - sec^2\theta )`

Using Identity :-

`\sf\implies sec^2\theta - tan^2\theta =1`

So that ,

`\sf\implies tan^2\theta -sec^2\theta = -1`

Substitute the value :-

`\sf\implies 3(tan^2\theta - sec^2\theta ) \\\\\sf\implies 3 *(-1) =\boxed{\red{\sf -3}}`

Hence the required answer is -3 .
