What You NEED To Know In Calculus
b ∫ f(x)dx = F(b) – F(a) a The fundamental theorem of calculus is used to evaluate definite integrals using antiderivatives. It is central to the evaluation of integrals, allowing you to find the area under a curve or between two functions. If f is continuous at every point of [a, b], and if F is any antiderivative of f on [a, b] then:
3 3 ∫ ∫ (x3 + 1)dx (x3 + 1)dx -1 -1 ] 3 x4 4 -1 Example: Find Antiderivative evaluated at 3 = + x Antiderivative evaluated at -1 Antiderivative of (x3 + 1) (81 / 4 + 3) – (1 / 4 – 1) = = 24
This rule is used in calculus when you want to find the derivative of a function that is a quotient. Hi Lo LoDeHi-HiDeLo Lo2
Example: Find f’(x)=x -1 x +1 Hi=x -1 DeHi=2x Lo=x +1 DeLo=2x F’(x)= (x +1) (2x)-(x -1)(2x) (x +1)2 2 2 2 2 2 2 2
The Chain Rule applies whenever there is a function that is formed from two simpler function. F(x)= g(h(x)) >>>> F(x)= g’(h(x)) h’(x)
Example: (sin(2x))’=2sin(x)cos(x) (sin(2x))’=2(sin’(x)cos(x)+sin(x)cos’(x)) (sin(2x))’=2(cos2(X)-sin2(x)) (sin(2x))’= 2cos(2x)
Jerk! f’’’(x)
To get the Jerk of an equation is to take the derivative of that equation 3 separate times. f’’’(x)
Example: Find the Jerk of 4x5. 1st Der.: 20x4 2nd Der.: 80x3 3rd Der.: 240x2
