Do you need to prove that it is equal?
If so:
SinA/cosA + sinB/cosB = (sinAcosB + sinBcosA)/cosAcosB
(SinAcosB + sinBcosA)/cosAcosB = (SinAcosB + sinBcosA)/cosAcosB
Answer:
Proved below
Step-by-step explanation:
If we assume that n + 1 even when n is even, it means that;
n + 1 = 2x
Where x is an integer
Then;
n = 2x - 1
This means that n is odd because 2x - 1 is odd.
But we know that n is even, thus, our assumption is wrong.
Therefore, n + 1 is odd when n is even.
