What are 3 differences between the sinusoidal functions? What are 3 similarities between the sinusoidal functions?

1. DIFFERENCES :

a) The Cosine is the Complementary trigonometric function of the sine.

b) The sine is ratio of the leg opposite the angle and the hypotensue while cosine is the ratio of the adjacent leg and hypotenuse

c) Sine is an odd function while cosine is an even function.

2. SIMILARITIES

a) Both sine and cosine have same Amplitude (which is 1)

b) Both sine and cosine have same time period (which is 2*pi)

c) Both sine and cosine have same domain (which is all real values)
