In these graphs of sine functions, x stands for theta on the unit circle and is the independent variable. When you graph, say, "y = sin (x+10)", you are plotting the value of "sin (x+10 radians)" at the x coordinate "x radians".

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 :) WebPeriod and frequency are reciprocals of each other in Physics, i.e. P = 1/f and f = 1/P. When discussing the graphs of trig functions, the Period is the length of a cycle. The term "frequency" is not formally defined. For example, sin (x) has a period of 2pi, since sin (x) = sin (x + 2pi) and it is the smallest angle for which that is true. 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. lithuania nightclubs

WebAt x = 0, sine starts at 0 and goes up to 1, while cosine starts at 1 and goes down. Think about what happens on the negative side though. On the sine graph, for negative x's you are getting negative y's, as it passes below the x-axis, while the cosine keeps giving you positive y's as it starts down toward the x-axis.

"WebSine and cosine are related to circles but are not made of circles. Recall the definition of sine is based on a right triangle inside a circle. sin = opposite / hypotenuse, and cos = adjacent / hypotenuse (SOH CAH TOA).
