|
Finding Critical Values |
if f'(c) = 0, the point C, (c,f(c)), is a critical value; setting the function to 0 and solving for x will give you all the Critical Values. |
Point C test |
|
finding Points of Inflection
|
With c being a critical value: if f"(c) = 0, then the point C, (c,f(c)), is a point of inflection. |
Point C test |
|
Finding Relative Maxs and Mins |
If a Critical Point, c, is not a point of inflection, it is a relative max or min: If f"(c) > 0, the point is a min. If f"(c) < 0, the point is a max. The max may also be the end of the function, so check there to get every max/min. |
Point C test |
|
Finding Absolute Maxs and Mins |
An absolute max or min is the highest or lowest point in a function, respectively. You can find this by finding all the relative maxs and mins and choosing the ones with the highest and lowest y-values, respectively. |

|
Tangent lines |
A tangent line is a linear line with the slope of the point it intersects on a function. if a tangent line crosses the point n on a function f(x), the equation can be found easily using point-slope form: (y-f(n))=f'(n)(x-n) < |
What is a tangent line? What is the equation of a tangent line on a function, f(x), crossing through the point n? |
|
Normal lines |
A normal line is a linear line perpendicular to the line it intersects on a function; this means its slope is a negative reciprocal of the intersecting points' derivative. if a normal line crosses the point n on a function f(x), the equation can be found easily using point-slope form: (y-f(n))=-(1/f'(n))(x-n) < |

|
What is the formula to estimate the area under a curve WITHOUT integrals? |
in the interval [a,b], the area under the curve will be calculated using areas of trapezoids, the "Y"'s are the placements of the trapezoids; the intervals. Decide the number of trapezoids, the more the better, find the trapezoids, then plug all the coords. and things into the equation. |
