Q
Trig function
A
y = asinbx + c
a = amplitude b = period c = y-intercept
8
Q
Amplitude
A
How much the function moves vertically from its midpoint (ie an amplitude of 3 moves 3 units up and down from its midpoint)
9
Q
Period
A
How frequently the function repeats itself
Period is NOT b, b is a coefficient
Period = 360/b
