Daniel sketched the graphs at right for 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 is y = sin⁡ θ and which is y = cos⁡ θ.

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
