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 Witryna- cos^-1 is the inverse of cos (1/cos) and - secant is also 1/cos But my math teacher says they're different. ... ^-1 = cos(1/x) sec(x) = 1/cos(x) Comment Reply Start Topic.

Witryna20 gru 2024 · Figure 1.7.3.1: Diagram demonstrating trigonometric functions in the unit circle., \). The values of the other trigonometric functions can be expressed in terms of x, y, and r (Figure 1.7.3 ). Figure 1.7.3.2: For a point P = (x, y) on a circle of radius r, the coordinates x and y satisfy x = rcosθ and y = rsinθ. 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. Witryna19 lis 2024 · Does the secant equal 1 over the sine or 1 over the cosine?
