+# Summary
+* $x=A\cos(2\pi ft)$ for when object starts at max displacement (cos(0) = 1)
+* $x=A\sin(2\pi ft)$ for when object starts at equilibrium (sin(0) = 0)
+* Velocity is largest at equilibrium, acceleration is largest at turning points.
+* Amplitude does not affect period.
+* Velocity time graphs are shifted by a quarter period from displacement.
+* Acceleration time graphs are shifted by half a period.
+* Reading zeros and extrema tells position, direction of motion, and whether the object is speeding up or slowing down.
