graphDaniel sketched the graphs at right for y = sinθ and y = cosθ.

Unfortunately, he forgot to label the graphs, and now he cannot remember which graph goes with which equation. Explain to Daniel how he can tell (and remember!) which graph y = sinθ and which is y = cosθ. Homework Help ✎

Look at the y-intercepts. What is cos(0°)? sin(0°)?
