If the function ๐‘“๐‘“(๐‘‘๐‘‘) is continuous on [๐‘Ž๐‘Ž, ๐‘๐‘], and y is a number between ๐‘“๐‘“(๐‘Ž๐‘Ž) and ๐‘“๐‘“(๐‘๐‘), then there exists at least one number ๐‘‘๐‘‘ = ๐‘๐‘ in the open interval (๐‘Ž๐‘Ž, ๐‘๐‘) such that ๐‘“๐‘“(๐‘๐‘) = ๐‘ฆ๐‘ฆ.

Mean Value Theorem

If the function ๐‘“๐‘“(๐‘‘๐‘‘) is continuous on [๐‘Ž๐‘Ž, ๐‘๐‘], AND the first derivative exists on the interval (๐‘Ž๐‘Ž, ๐‘๐‘) then there is at least one number ๐‘‘๐‘‘ = ๐‘๐‘ in (๐‘Ž๐‘Ž, ๐‘๐‘) such that ๐‘“๐‘“โ€ฒ(๐‘๐‘) = ๐‘“๐‘“(๐‘๐‘)โˆ’ ๐‘“๐‘“(๐‘Ž๐‘Ž)

Curve Sketching And Analysis

Derivative of an Inverse Function: If f has an inverse function g then:

๐‘”๐‘”โ€ฒ(๐‘‘๐‘‘) = 1

๐‘“๐‘“โ€ฒ(๐‘”๐‘”(๐‘‘๐‘‘))

derivatives are reciprocal slopes

Implicit Differentiation

Remember that in implicit differentiation you will have a ๐‘‘๐‘‘๐‘‘๐‘‘

๐‘‘๐‘‘๐‘‘๐‘‘ for each y in the original

function or equation. Isolate the ๐‘‘๐‘‘๐‘‘๐‘‘๐‘‘๐‘‘๐‘‘๐‘‘

. If you

are taking the second derivative ๐‘‘๐‘‘2๐‘‘๐‘‘

๐‘‘๐‘‘๐‘‘๐‘‘2 , you

will often substitute the expression you found for the first derivative somewhere in the process.

First Derivative:

๐‘“๐‘“โ€ฒ(๐‘‘๐‘‘) < 0 function is decreasing.

๐‘“๐‘“โ€ฒ(๐‘‘๐‘‘) = 0 or DNE: Critical Values at x.

Relative Maximum: ๐‘“๐‘“ โ€ฒ(๐‘‘๐‘‘) = 0 or DNE and sign of ๐‘“๐‘“โ€ฒ(๐‘‘๐‘‘) changes from + to โˆ’ .

Relative Minimum: ๐‘“๐‘“ โ€ฒ(๐‘‘๐‘‘) = 0 or DNE and sign of ๐‘“๐‘“โ€ฒ(๐‘‘๐‘‘) changes from โˆ’ to + .

Absolute Max or Min: MUST CHECK ENDPOINTS ALSO

The maximum value is a y-value.

Second Derivative:

๐‘“๐‘“โ€ฒโ€ฒ(๐‘‘๐‘‘) > 0 function is concave up.

๐‘“๐‘“โ€ฒโ€ฒ(๐‘‘๐‘‘) < 0 function is concave down.

๐‘“๐‘“โ€ฒ(๐‘‘๐‘‘) = 0 and sign of ๐‘“๐‘“โ€ฒโ€ฒ(๐‘‘๐‘‘) changes, then there is a point of inflection at x. Relative Maximum: ๐‘“๐‘“โ€ฒโ€ฒ(๐‘‘๐‘‘) < 0 Relative Minimum: ๐‘“๐‘“โ€ฒโ€ฒ(๐‘‘๐‘‘) > 0

The derivative of position (ft) is velocity (ft/sec); the derivative of velocity (ft/sec) is acceleration (ft/sec2). The integral of acceleration (ft/sec2) is velocity (ft/sec) ; the integral of velocity (ft/sec) is position (ft).

Speed is | velocity |

If acceleration and velocity have the same sign, then the speed is increasing, particle is moving right.

If the acceleration and velocity have different signs, then the speed is decreasing, particle is moving left. Displacement = โˆซ ๐‘ข๐‘ข(๐‘ก๐‘ก) ๐‘‘๐‘‘๐‘ก๐‘ก๐‘ก๐‘ก๐‘“๐‘“

ONLY FOUR THINGS YOU CAN DO ON A CALCULATOR THAT NEEDS NO WORK SHOWN:

1. Graphing a function within an arbitrary view window.

2. Finding the zeros of a function. 3. Computing the derivative of a function numerically. 4. Computing the definite integral of a function

numerically.

โ€œthe rate of change of y is proportional to yโ€

When solving a differential equation:

1. Separate variables first

2. Integrate

3. Add +C to one side

4. Use initial conditions to find โ€œCโ€ 5. Write the equation if the form of ๐‘ฆ๐‘ฆ = ๐‘“๐‘“(๐‘‘๐‘‘)

The Accumulation Function

๐‘Ž๐‘Ž

The total amount, ๐น๐น(๐‘‘๐‘‘), at any time ๐‘‘๐‘‘ , is the initial amount, ๐‘“๐‘“ (๐‘Ž๐‘Ž), plus the amount of change between ๐‘ก๐‘ก = ๐‘Ž๐‘Ž and ๐‘ก๐‘ก = ๐‘‘๐‘‘, given by the integral.

A Riemann Sum means a rectangular approximation. Approximation means that you DO NOT EVALUATE THE INTEGRAL; you add up the areas of the rectangles.
