Simplify the expression by using a double-angle formula or a half-angle formula. (a) 2 tan(5°) 1 − tan2(5°)

The question is related to trigonometry and we have to use the formula of double angle .

Here we use double angle formula of tangent function which is

Given expression is

Comparing it with double angle formula, we will get x = 5

SO the required expression is equal to

So the answer is tan(10) .

add the table and i will answer correctly

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )
