QuestionRewrite sin61\sin 61^{\circ} using its cofunction. What is sin61=\sin 61^{\circ}=? (Provide the answer without the degree symbol.)

Studdy Solution
Now, subtract 6161^{\circ} from 9090^{\circ} to find the angle for cosine.
cos(9061)=cos(29)\cos(90^{\circ} -61^{\circ}) = \cos(29^{\circ})So, sin61\sin61^{\circ} can be rewritten as cos29\cos29^{\circ}.
