WebGIF (1) = 1 and by the same definition, GIF (1.1) = 1, GIF (1.2) = 1, etc. So by the definition of continuity at a point, the left and right hand limits of the GIF function at integers will always be different - therefore, no limit will exist at the integers, even though integers are in the domain of the function. Hope this helps :) WebSo, the time axis is down here. When the green arrow hits zero right there, the value of the cosine was one, and when it's minus 180 degrees it's minus one on the cosine. So, that's why this is cosine wave. And, it has the same frequency as the sine wave we generated.

WebA graph of a trigonometric wave on an x y coordinate plane. The x and y axes scale by one. There is a point on the highest part of the graph labeled (negative two pi, three). There is a point on the lowest part of the graph nearest to the previously mentioned point at the point (negative pi over two, negative four). WebMar 14, 2014 · For example, let's say that we are looking at an angle of π/3 on the unit circle. The value of sin (π/3) is ½√3 while cos (π/3) has a value of ½.

That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. For more explanation, check this out.

WebIf, instead of thinking about the x and y coordinates of points on the unit circle, you decide to plot a graph with angle on the x-axis, with the y axis being the cosine or sine of the variable x, you will obtain a pattern like the one in this video. So, this is the video where Sal is showing you what the trig functions look like.

WebBoth the normal sine and cosine functions sway between 1 and -1. When you add a coefficient, you are multiplying that positive one or negative one by the coefficient, giving you a new amplitude equal to the absolute value of your coefficient.

In the video I used the negative of the angle: theta - 90 = - (90 - theta) This version of the formula gives the same answer. The reason is because cosine is an "even" function.
