Choose trig functions to model periodic phenomena using amplitude, frequency, and midline.

Find and verify sinusoidal maximum and minimum values

Problem

For \(y~=~3\sin(x)~+~7\), use the envelope diagram to state the amplitude, midline, maximum, minimum, and range, then verify the midpoint and half-range relationships.

Big Picture

What this problem is really about

A sinusoid's vertical envelope is centered at its midline and extends one amplitude in each direction. Read amplitude as the absolute value of the trig coefficient, then add and subtract it from the vertical shift to obtain the extreme outputs and closed range. Averaging those extremes should recover the midline, while half their difference should recover the amplitude.
