Simplify the expression by using a double-angle formula or a half-angle formula. (a) 2 tan(5°) 1 − tan2(5°)
antoniya [11.8K]

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

tan(2x) = \frac{2tan(x)}{1-tan^2(x)}

Given expression is

\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}

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

SO the required expression is equal to

\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}  =tan(2*5 )

\frac{2tan (5 \degree)}{1-tan^2(5 \degree)}  =tan(10 )

So the answer is tan(10) .
