Final Flashcards
1
Q
a and b in exponential functions…
A
a cannot be 0, b cannot be 1
2
Q
a and b in logarithmic functions…
A
a cannot be 0, b cannot be negative
3
Q
when solving logs, remember…
A
to check for extraneous solutions!
any negatives or zero.
4
Q
coordinates of point p
A
(cosr, sinr)
5
Q
what does the AROC of a polar function tell us?
A
the rate at which the radius is changing per radian
6
Q
inverse variation
A
If x is inversely proportional to y…
y=k/x
k is a constant of proportionality
7
Q
logs are inverses if…
A
log(b)b or if
b^log(b)
8
Q
linear model for a semi-log plot
A
given the exponential model y=ab^x, the linear model for the semi-log plot is y=logbx+loga
– the base of the logs is the base of the axis
9
Q
to find c
A
- see translation from origin
2.b(max(x value)+c)=regular max x value
–cos: 0
–sin: pi/2
