Hello. I'm currently having problems on trying to find the intersection point of these two trig graphs:
a(t) = -175cos(0.23t) - 75
b(t) = 172sin(0.23t) - 80
0 ≤ t ≤ 30
Well, I assume this would be the first step:
-175cos(0.23t) - 75 = 172sin(0.23t) - 80
Now, I am finding it difficult to do the rest.
Looks like simple algebra to get the t by itself but it's proving to be harder than I anticipated.
I know the answers (using my graphics calculator to find the points) and they are:
(10.12,45.1) and (23.95,-200.19)
Any help is of course, appreciated.
