11-06: Sinusoidal Functions

Amplitude

the distance from the axis to the peak or trough.

axis

the mean between the peak and trough (halfway)

Trough

the minimum point.

Peak

Period

Periodic Function

a function that repeats itself at regular intervals

Equation of the axis

the mean between the peak and trough

sin functions - shape/order

cos functions - shape/order

max, axis, min, axis, max

find a (amplitude)

a = (max-min)/2

find c (equation of the axis)

c = (max + min)/2

find max

c+|a| = max

find min

c-|a| = min
