someone help

Answer 3

cosine ---> coSINE

Answer 4

so y=cos(x) because its a SINusoid, and its coSINE?

Answer 5

yes a sinusoid is shaped like sine or cosine

a wavy curve that goes up and down forever repeating the same thing over and over

Answer 6

cosine is simply a phase shift of sine

cos(x) = sin(90-x)
