TEST Flashcards
What does the second derivative give you? F’‘(x) = 0
PPOI, and concavity
How do you give reason for your answers?
B/c f’(x) > 0
If a trinomial doesn’t factor, try
Quadratic formula
It is only a POI if
There is a change in sign
To test an inc or dec, plug into
Derivative
To find the relative max and min points
Plug the x into the ORIGINAL function to get the y
When looking for abs max or min, look at
Y values on the t chart you create
Watch out for the interval
Just remember
When looking at derivative graph, look for
CN, INC DEC, and concavity. Also relative max and min
INC or DEC with derivative graph, look at
VALUES
concavity on derivative graph
Look at where the curve is increasing or decreasing
Minimum and maximum in the derivative graph
Number line with the CN
Reimann sum Under the curve means
Smaller numbers
Riemann sum over curve means
Larger numbers
Trapezoidal rule formula
1/2 h (b1 + b2)
