Hello! I have two problems I need help on.
use sum or difference to find the exact value of each trigonometric function.
I know this equals= 4(360)+255
and 255 is 210+45
So I did
Which gives me -3.739 But I am quite sure this is wrong.(Giggle)
my second problem is
cos(x+y)= tanx(5/3) and sin y=1/3
I am quite confused on this one
Can anyone help me with these problems?
