tan(θ) = sec(θ)/√(sec²(θ) - 1)(因为 sin²(θ) + cos²(θ) = 1,所以 sin(θ) = √(1 - cos²(θ)),进而得到这个关系) 英文表述: tan(θ) is defined as sin(θ)/cos(θ), the sine function divided by the cosine function. sec(θ) is defined as 1/cos(θ), th...
Therefore, we can say that sec^2(x) = 1 + tan^2(x). This relationship can be further illustrated with an example. Let's consider a right triangle with an angle x.The secant of angle x is equal to the length of the hypotenuse divided by the length of the adjacent side, while the...

In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just 'sec'. sec x = H A Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used....
