Question 978679: let theta be an angle in the first quadrant, and suppose sin (theta) = a. Evaluate the following expressions in terms of a.
(a) sin(θ+360∘)=
(b) cos(90∘−θ)=
(c) sin(180∘−θ)=
(d) sin(360∘−θ)=

(a) sin(θ+360°) = sin(θ) = a;
(b) cos(90°−θ) = sin(θ) = a;
(c) sin(180°−θ) = sin(θ) = a;
(d) sin(360°−θ) = -sin(θ) = -a;
(e) cos(270°−θ) = -sin(θ) = -a.
