Web"y" is taken as the equal to cos (theta) because that is what you are measuring. remember the "x" axis is actually the "theta" axis. you you are graphing where cos (theta) is when theta is at a specified value. so x-axis=theta and y-axis=cos (theta). if you were trying to find the sin (theta), this would be a different graph, then that would make … 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. importing cuban cigars https://wooferseu.com

Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. 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. literature works examplesWebFor a simple sine wave, the highest point of the snake will be 1 and the lowest point will be -1. After a little practice, cosine is easily identifiable because y = cos (x) passes through a value of 1 when the angle is 0. the highest point of the curve for y = cos (x) is also plus 1 and the lowest point is also -1. importing data from chrome to edgeWebOur old friends sine, cosine, and tangent aren’t up to the task.
