| optimization | minimum or maximum problem |
| critical point | local minimum or maximum |
| cosh^-1(x) | ln[x + √(x^2 - 1)] |
| essential discontinuity | curve has a vertical asymptote |
| L'hopital's rule |
lim (x->c) f(x)/g(x) = f'(x)/g'(x) only for indeterminate functions (equal 0/0 or ∞/∞) so basically solve them separately |
| cosh x | e^x + e^-x / 2 |
| jump discontinuity |
curve "breaks: and starts somewhere else (left limit doesn't equal right limit) |
| Profit | Revenue - cost usually written as pi |
| sigma notation |
definite integral number at the top tells the number of intervals number at the bottom tells where to begin |
| y=e^i(x-a)^2 | a shifts the graph left or right divide (x-a)^2 by b and b makes the graph wider or narrower |
| y=e^i(x-a)^2 |
a shifts the graph left or right divide (x-a)^2 by b and b makes the graph wider or narrower |
| trapezoid rule | b-a/2n [f(xo) + 2f(x1) + 2f(x2) ... f(xn)} |
| average value | 1/b-a integral from b to a f(x) dx |
| y=a(1-e^-bx) | a is the asymptote and b is the stretch or shrink of the graph |
| delta t |
b-a/n n is the number of intervals and b and a is the interval |
| y=a(x-h)^2 + k | a is stretch or shrinkh shifts right and leftb shifts up and down |
| slope of a line = | y2 - y1 / x2 -x1 |
| y=a(x-h)^2 + k |
a is stretch or shrink h shifts right and left b shifts up and down |
| hyperbolic functions to know | cosh(0) = 1sinh(0) = 0cosh(-x) = cosh x sinh (-x) = -sinh x cosh^2 x - sinh^2 x = 1 |
| Extreme Value theorem | if f is continuous then must have a global max and global min on the closed interval |
| A function is | a relation in which each element of the domain (x value - independent variable ) is paired with only one element of the range ( y value - dependent variable ) |
| A function is | A relation can be tested to see if it is a function by the vertical line test. Draw a vertical line through any graph, and if it hits an x-value more than once, it is not a function. |
| equation of a line | y - y₁ = m ( x - x1 ) |
