How do you know if a graph is sine or cosine
WebIt is a circle with a radius of 1 with its center at 0. Because the radius is 1, we can directly measure sine, cosine and tangent. Here we see the sine function being made by the unit circle: Note: you can see the nice graphs made by sine, cosine and tangent. Degrees and Radians Angles can be in Degrees or Radians. Here are some examples: WebTo stretch a graph vertically, place a coefficient in front of the function. This coefficient is the amplitude of the function. For example, the amplitude of y = f (x) = sin (x) is one. The amplitude of y = f (x) = 3 sin (x) is three. Compare the two graphs below. Figure %: The sine curve is stretched vertically when multiplied by a coefficient
