7-65.

*y* = sin*θ* and *y* = cos*θ*.

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* = sin*θ* and which is *y* = cos*θ*. Homework Help ✎

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