Which expression is equivalent to (sin x + 1)(sin x − 1)?

1 answer:

8 0

Please be careful in the future regarding the options. These options look like cos of 2x, rather than cos(squared) of x.

The answer is B) -cos²(x)

(sin(x) + a) (sin(x) - a) = -cos²(x)

Answer:

Step-by-step explanation:

You can see that this sequence is geometric so you need to know the geometric sequence which is $x_{n} =r^{n-1}$ and if you plug in every thing you get $x_{n}$ = $2^{99-1}$ which would be $2^{98}$ which is 316,912,650,057,057,350,374,175,801,344
