Review slope fields by reading local slopes, sketching solution curves and estimating behaviour through a given point across successive intervals.
The depth of seawater at a location can be modeled by the function H that satisfies the differential equation dtdH=21(H−1)cos(2t), where H(t) is measured in feet and t is measured in hours after noon ( t=0 ). It is known that H(0)=4.
A portion of the slope field for the differential equation is provided. Sketch the solution curve, y=H(t), through the point (0, 4).

A portion of the slope field for the differential equation is provided. Sketch the solution curve,
y=H(t), through the point (0, 4).
Solution curve 1 point
Scoring notes:
- The solution curve must pass through the point (0,4), extend to at least t=4.5, and have no
obvious conflicts with the given slope lines.
- Only portions of the solution curve within the given slope field are considered.
