How do you know if a graph is sine or cosine
WebMay 1, 2016 · 0 The diagram shows part of the graph of a function whose equation is y = a sin ( b x ∘) + c (a) Write down the values of a, b and c. (b) Determine the exact value of P where the graph intersects the x-axis as shown in the diagram. For part a, I can say that the amplitude is 2 because it covers 1 to -3. 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
How do you know if a graph is sine or cosine
Did you know?
WebFeb 13, 2024 · Earlier, you were asked how an equation changes when a sine or cosine graph is stretched by a factor of 3 . If a sine graph is horizontally stretched by a factor of 3 then the general equation has \(b=\frac{1}{3}\). This is because \(b\) is the frequency and counts the number (or fraction) of a period that fits in a normal period of \(2 \pi\). WebApr 25, 2013 · Comparing y = sin x and y = cos x (below), we see that the curves are almost identical, except that the sine curve starts at y = 0 and the cosine curve starts at y = 1. If …

We discuss sine and cosine equations in this free math video tutorial by Mario's … 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:
WebPhase Shift is a shift when the graph of the sine function and cosine function is shifted left or right from their usual position or we can say that in phase shift the function is shifted horizontally how far from the usual position.
