Q
Graphing Sine or Cosine Functions with Different Coefficients
A
The coefficients in the functions y = a sin(bx) or y = a cos(bx) determine the amplitude and period of the functions.
• The amplitude of the function y = a sinx or y = a cosx is equal to |a |.
• The period of the function y = sin(bx) or y = cos(bx) is equal to 2pi/b
