This is like the preceding problem, except that you need to get all answers correctly to get credit.
Suppose $$\cos u = \frac{3}{5}$$ and $\sin u$ is positive.
$\sin(u) =$
$\sin\left(u-\pi\right) =$
$\cos\left(u-\pi\right) =$
$\sin\left(u-\frac{\pi}{2}\right) =$
$\cos\left(u-\frac{\pi}{2}\right) =$
