A trough of water is 8 meters deep and its ends are in the shape of isosceles triangles with widths of 5 meters and heights of 2 meters.
Water is being pumped IN at a constant rate of 6 m3/sec. At what rate is the height of the water changing when the water is 120 cm high?
Sec 3.10: Linear Approximations and the Differential
What we've done... Given f(x)
Find the equation of the tangent line at x = a.
If we use a tangent line to approximate function values, then we are using a LINEAR APPROXIMATION.
Use a linear approximation to approximate .
