Unformatted text preview: b. cos(3 x ) + sin(3 x ) = 3 x This is a conditional equation c. sin(2 x ) + sin 2 ( x ) = 2 This is a contradiction 2. Verify the following identity (4 points). 1 csc sin sec cos = + u u u u . We begin with the left-hand side. u u u u u u u u sin 1 sin cos 1 cos csc sin sec cos + = + RHS u u u u u u = = + = + 1 sin cos sin 1 sin cos 1 cos 2 2...
