Unit 7 - Derivatives of Trigonometric Functions. We have seen that differential calculus can be used to determine the stationary points of functions, in order to sketch their graphs. If each number is greater than $\text{0}$, find the numbers that make this product a maximum. d&= \text{ days} These concepts are also referred to as the average rate of change and the instantaneous rate of change. We have learnt how to determine the average gradient of a curve and how to determine the gradient of a curve at a given point. Just because gravity is constant does not mean we should necessarily think of acceleration as a constant. I’ve tried to make these notes as self contained as possible and so all the information needed to read through them is either from an Algebra or Trig class or contained in other sections of the notes. x��\��%E� �|�a`�/p�ڗ_�� K|`|Ebf0��=��S�O�{�ńef2��ꪳ��R��דX��?��z2֧�䵘�0jq~��~��O�� The ball hits the ground at $\text{6,05}$ $\text{s}$ (time cannot be negative).

We can check that this gives a maximum area by showing that ${A}''\left(l\right) < 0$: A width of $\text{80}\text{ m}$ and a length of $\text{40}\text{ m}$ will give the maximum area for the garden. The coefficient is negative and therefore the function must have a maximum value. \therefore \text{ It will be empty after } \text{16}\text{ days} Michael has only $\text{160}\text{ m}$ of fencing, so he decides to use a wall as one border of the vegetable garden. Calculate the width and length of the garden that corresponds to the largest possible area that Michael can fence off. During an experiment the temperature $T$ (in degrees Celsius) varies with time $t$ (in hours) according to the formula: $T\left(t\right)=30+4t-\frac{1}{2}{t}^{2}, \enspace t \in \left[1;10\right]$. \begin{align*} \end{align*} Germany.
