Answer is choice C) cosine is even; sine is odd
The properties that come with even and odd functions are...
f(-x) = f(x) indicates we have an even function. So cos(-x) = cos(x)
f(-x) = -f(x) indicates we have an odd function. So sin(-x) = -sin(x)
note: the end result of the proof will lead to cos(A)cos(B)+sin(A)sin(B)
Answer:
B
Step-by-step explanation:
the answer is b because the they are only 5 numbers of student that check in for assignment details
You gather the like terms together.
if you have -3y +2x +6w -4 + 3y -5x +2w
you put the like terms together
so for the term y:
you have -3y +3y = 0
for x:
2x - 5x = -2x
for w:
6w + 2w = +8w
and you also had -4. if you put them together you get
0 -2x +8w -4
which is
-2x +8w -4
