Answer:
d
Step-by-step explanation:
What does sin equal to?
sin is equal to s(x) just like in f(x) in functions. The value of S will be multiplied by the rate -> X.
What does cos equal to?
Just like in sin, cos is equal to c(x). This time, the integers are a lot different to compare many things as a function(rate) using the same format.
Remember, just like in variables, Sin + Cos = 1 since we do not know the value of them yet, meaning that they will always equal to one, but it can change proportionally when using s(x) or c(x) since the X multiplied to the sin and/or cos can change the value.
Now, use your knowledge to factor it out like in factoring polynomials:
Sin B + cos C
Sin(B + C) (I added just C in the brackets since that means cos C, it would be confusing to add CC).
= SinB (Cos C) + CosB(Sin C) <- We flipped it around but they are still equal!
The answer is one and since we represented this value above again, we get 1 + 1 = 2.
