A satellite is dropping back to Earth. The distance it has fallen, \(D\) metres, since first spotted is given by \(D(t) = 100t + 5{t^2}\), where \(t\) is the length of time in seconds since first ...
To find the maximum or minimum values of a function, we would usually draw the graph in order to see the shape of the curve. Now, using our knowledge from differentiation, we can find these ...
