Trigonomic Preliminaries
Howdy guys, I have a specialist maths project due tommorow, and I need some help.
I have to add these two functions:
C(t) = 10 cos((PI*t)/6) +9
and
F(t) = 5 sin ((PI*t)/6)+2.2
So that they equal P(t). Could someone please explain how to do this?

Re: Trigonomic Preliminaries
P(t) = C(t) + F(t)
P(t) = 10 cos((PI*t)/6) +9 + 5 sin ((PI*t)/6)+2.2
That's my first reaction to what you stated, but I have a feeling it's more complicated than that, so please explain further.

Ops, never mind, it was easier than I thought. Thanks anyway though JoshDick!
FYI, you were right, it just simplifies to
10 cos((PI*t)/6) + 5 sin ((PI*t)/6)+ 11.2
Which I thought would be much more complicated, but he said thats all we need to do.
