Theorems and chapter three Flashcards
The mean value theorem
If function f is continuous on the closed interval a,b and differentiable on the open interval a,b then for some value C between a and b,
f’c=f(b)-f(a)/b-a
**once you find it this way, set the derivative equal to f’c to find x
Rolles Theorem
If function f is continuous on the closed interval a,b and differentiable on the open interval a,b and f(a)=f(b) then for some value between a and b f’(c)=0
Extreme value theorem
remLet f be a continuous function on the closed and bounded interval a,b. then f assumes both a max and min value somewhere on a,b
To find whether an object is speeding up or slowing down,
velocity and acceleration must have different signs
To find absolute max and min, use
EVT
use the end points of the interval and the critical values
Concave up if
f’‘(x) is greater than 0
Concave down if
f’‘(x) is less than 0
