New cards
Amplitude
the distance from the axis to the peak or trough.
2
New cards
axis
the mean between the peak and trough (halfway)
3
New cards
Trough
the minimum point.
4
New cards
Peak
5
New cards
Period
6
New cards
Periodic Function
a function that repeats itself at regular intervals
7
New cards
Equation of the axis
the mean between the peak and trough
8
New cards
sin functions - shape/order
9
New cards
cos functions - shape/order
max, axis, min, axis, max
10
New cards
find a (amplitude)
a = (max-min)/2
11
New cards
find c (equation of the axis)
c = (max + min)/2
12
New cards
find max
c+|a| = max
13
New cards
find min
c-|a| = min
