There is a section on my worksheet that says
"Rewrite each expression in terms of the sine, cosine, or tangent using the addition and subtraction identities. Simplify each result."
I don't understand what I am suppose to do for that section.
first two problems:
sin(5pi/2 + t)
and one more thing for another section i am suppose to be finding sin2t cos2t and tan2t
if sin t = 4/5, t in Q I
is this correct
sin2t = 8/5
cost2t = 6/5
tan2t = 8/3???
thanks in advance
