Find the indefinite integral.
sin 60 V cos 60 de
Step 1
To solve the integral
sin 68 cos 60 de, rewrite the integral as
2
sin
60 V cos 6e sin 60 de.
Use the trigonometric identity
sin e + cos e =
/(- cos*60
sin 60 Vcos 60 sin 60 de =
(cos (60))? |)V cos 60 sin 60 de.
Therefore,
CoS
Step 2
Simplify the right side.
sin 60 Vcos 60 sin 66 de =
os1/2
5/2
60 - cos
5/2
60 sin 60 de
Step 3
Substitute cos 60 = u.
Differentiate with respect to 0 on both sides.
-1/6
sin 60 de = du
