Question: If a ( t ) = c o s ( 2 t - 2 0 ) , b ( t ) = - 3 s

If a(t)=cos(2t-20),b(t)=-3sin(2t+20), and c(t)=2sin(2t+110), and you were to add all three terms together write down the final answer. You must show all work. Hint - you can try to approximate it first, but the answer must be calculated.
