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) .

Need help quick simplify the expression (-4) power of 3
dezoksy [38]

Answer:

-64

Step-by-step explanation:

The question is asking to solve (-4)^3

Notice how the -4 is in parenthesis. This means that along with the 4 being multiplied, the negative is too.

(-4)^3 is the same as -4 · -4 · -4

First let's figure out if this will be negative or positive

Whenever the exponent is odd and there is a negative in the parenthesis the answer will be negative and if its even it will be positive

Now find out what 4 x 4 x 4 equals (64)

In conclusion the answer is -64
