Determine if the following limits exist and if so their value:
limx®1 [(x2-3x+2)/(x2-1)]
limx®¥ [(3x2+sin(x))/(1-x2)]
limx® 0 [(cos(x)-1)/x]
limx® 3- [1/(x2-9)]
Using the definition of derivative and properties of
limits, compute f¢(1) where f(x): = 2+x-x2.
Determine derivatives for each of the following
functions:
f(x) = (x2-1),
[Ö(3x3-4x+1)]
[Ö(sin(3x2))]
Using differentials, estimate cos(.05).
If the width of a rectangle is changing at a rate of
twice its length and its length is changing at a rate of +5 cm/sec,
then at what rate is the area of the rectangle changing?
Consider the function
f(x) = x3-x2-x+2, -2 £ x £ 4.
Determine the intervals where f is increasing and
where it decreases.
Determine the critical points for the function.
Determine the intervals where f is concave up and
where it is concave down.
Specify which points are local maxima, local minima,
or inflection points.
Sketch a graph of f using the information determined
above.
Evaluate each of the antiderivatives:
(2x2-3)(x2+2x)
x[Ö(3-x2)]
tan(x) sec(x)
Calculate the following definite integrals:
ò02 (x2-1)2 dx
ò01 x[Ö(3-x2)] dx
