Calculus Exam #2 Study Guide
d/dx [e^x] - ANS-e^x
d/dx [-2/3 e^(-1/2x)] - ANS--2/3 e^(-1/2x) * (-1/2)
(lim as h approaches 0) [(f(x+h)-f(x))/h] - ANS-Msec (average velocity)
If differentiable - ANS-it's continuous.
If continuous - ANS-not necessarily differentiable.
sin'x - ANS-cosx
cos'x - ANS--sinx
tan'x - ANS-sec^(2) x
cot'x - ANS--csc^(2) x
sec'x - ANS-(secx)(tanx)
csc'x - ANS--(cscx)(cotx)
arcsic'x - ANS-1/sq root(1-x^2)
arccos'x - ANS--1/sq root(1-x^2)
arctan'x - ANS-1/(1+x^2)
Instantaneous Rate of Change - ANS-Slope of tangent line, lim as h approaches 0
When s(t) is increasing - ANS-v(t) is positive
S(t) is increasing - ANS-(t) is positive
V(t) is increasing - ANS-a(t) is positive
s(t) is CCU - ANS-v(t) is increasing & a(t) is positive
s(t) is CCD - ANS-v(t) is decreasing & a(t) is negative
