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.

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.

Graph sinusoidal functions: phase shift (practice) Khan Academy

WebTheta is defined as the angle with sine y/r (= y), or with cosine x/r (= x). 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". 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.
