Use the cofunction identities to find an angle theta that makes the statement true. 1) sin(...

Use the cofunction identities to find an angle theta that makes the statement true.

1) sin( 3theta - 17degrees)=cos (theta+43degrees)

2) cot 5theta= tan 4theta

Use identities to write the expression as a single function of x or theta.

1) cos (theta - pi)

Verify that the equation is an identity.

1) sin (x+y)-sin(x-y)=2 cos x sin y
