Tangent, Cotangent, Secant, and Cosecant - Dartmouth

WitrynaThe trigonometric function are periodic functions, and their primitive period is 2π for the sine and the cosine, and π for the tangent, which is increasing in each open interval (π/2 + kπ, π/2 + (k + 1)π). At each end point of these intervals, the tangent function has a vertical asymptote . WitrynaIn this video, we will learn how to find the value of cosine of inverse of secant of x. It can also be said as to find out the value of cosine of arcsecant o... nt foot

Why does sec 0 equals 1? - Answers

WitrynaSecant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1 cos x. cosec x = 1 sin x cot x = 1 = cos x tan x sin x Witryna8 sty 2012 · The period is the length of x over which the equation repeats itself. In this case, y=sin x delivers y=0 at x=0 at a gradient of 1. y next equals 0 when x equals pi, but at this point the gradient is minus 1. y next equals 0 when x equals 2pi, and at this point the gradient is 1 again. Therefore the period of y=sinx is 2pi.
