aSuppose ga28cos07a5 For the value of cosine to vary through

a.Suppose g(a)=2.8cos(0.7(a+5)).

-For the value of cosine to vary through a complete cycle of its outputs, the value of the input of g must vary by _________ units.

b. Suppose g(a)=0.35sin(36a13).

-For the value of sine to vary through a complete cycle of its outputs, the value of the input of gg must vary by __________ units.

Solution

a.Suppose g(a)=2.8cos(0.7(a+5)).

period =2pi/0.7 =20pi/7

-For the value of cosine to vary through a complete cycle of its outputs, the value of the input of g must vary by __20pi/7_______ units.

b. Suppose g(a)=0.35sin(36a13).

period =2pi/36 =pi/18

-For the value of sine to vary through a complete cycle of its outputs, the value of the input of gg must vary by ___pi/18_______ units.
