Question 1

• The coefficients in the functions y = a sin(bx) or y = a cos(bx) determine the amplitude and period of the functions.

Answer 1

• The coefficients in the functions y = a sin(bx) or y = a cos(bx) determine the amplitude and period of the functions.

Question 2

• The amplitude of the function y = a sinx or y = a cosx is equal to |a|.

Answer 2

• The amplitude of the function y = a sinx or y = a cosx is equal to |a|.

Question 3

• The period of the function y = sin(bx) or y = cos(bx) is equal to (2pi)/|b|.

Answer 3

• The period of the function y = sin(bx) or y = cos(bx) is equal to (2pi)/|b|.
