1) dx Viewed as an equation to solve for y(x), this asks us to find the function whose graph has slope f (x) at the point x. So in order to solve this equation we ‘just’ have to find a function whose derivative is f (x). 1 The Fundamental Theorem of Calculus Any function F that satisfies F = f is called an anti-derivative1 of f . Clearly if F is an anti-derivative of f then so is F(x) + c for any constant c. This terminology allows us to distinguish between reversing the process of differentiation (finding an anti-derivative) and integration (finding the area under a curve).

11. A recent UK campaign to persuade drivers to cut their speed in town from 35 mph to 30 mph. mpg makes the point more forcefully. Exercises 37 does the shell travel before it hits the ground? 8 In Dallas on 22 November 1963, President Kennedy was assassinated; by Lee Harvey Oswald if you do not believe any of the conspiracy theories. Oswald fired a Mannlicher–Carcano rifle from approximately 90 m away. The sight on Oswald’s rifle was less than ideal; if the bullet travelled in a straight line after leaving the rifle (at a velocity of roughly 700 m/s) then the sight aimed about 10 cm too high at a target 90 m away.

3 Velocity, acceleration and Newton’s second law of motion Newton formulated the calculus, and his theory of differential equations, in order to be able to write down and solve the mathematical models that resulted from his laws of motion. Since derivatives are essentially the ‘rate of change’, questions concerning velocities (the rate of change of position) and acceleration (the rate of change of velocity) are most naturally framed as differential equations. 30 5 ‘Trivial’ differential equations Newton’s second law of motion states that the change p in the momentum p of an object is equal to F, the force applied, multiplied by the time t over which the force acts, p=F t.
