your range is 8, so you need
4cos ??
period = 360/k
360/k = 135
135k = 360
k = 8/3
so far we have
y = 4cos (8/3)Ø
that would give us a max value of 4, but we want our max to be 1, so we have to drop our curve by 3 units
final:
y = 4cos(8/3)Ø - 3
a) Determine the equation of a sine function that would have a range of {y€R|-7<(or equal) Y <(or equal) 1} and a period of 135degrees.
b) determine the cosine function that results in the same function an part (a).
Any help provided will be greatly appreciated.

Ok I was wondering why the zero with the slash was in the equation, i have never seen that before!
