(5 x 10^6)+(2 x 10^3)+(1 x 10^2)+(9 x 10^1)
We have:
Then we use trigonometric identities to change the negative sign of the trigonometric functions, so:
We clear f(x):
we simply what we can:
Thus, the correct answer is;
I think the answer is B. because it says "waste of time"
I would go with A but I am not 100% sure so you may want to check however you can.
Yes!
