In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles.

\sec x = \frac{1}{\cos{x}} \csc{x} = \frac{1}{\sin{x}} \cot{x} = \frac{1}{\tan{x}} 平方关系 \sin^{2}x + \cos^{2}x = 1. 1 + \tan^{2} x = \sec^{2}x. 1 + \cot^{2}x = \csc^{2}x. 商关系 \tan{x} = \frac{\sin{x}}{\cos{x}} = \frac{\sec{x}}{\csc{x}} \cot{x} = \frac{\cos{x}}{\sin{x}} = \frac{\csc{x}}{\sec{x}} 三角恒等变换公式 和差公式

sin ^2 (x) + cos ^2 (x) = 1 . tan ^2 (x) + 1 = sec ^2 (x) . cot ^2 (x) + 1 = csc ^2 (x) . sin(x y) = sin x cos y cos x sin y . cos(x y) = cos x cosy sin x sin y

Cosecant Function: csc (θ) = Hypotenuse / Opposite. Secant Function: sec (θ) = Hypotenuse / Adjacent. Cotangent Function: cot (θ) = Adjacent / Opposite. sin (θ) = 2/4, and csc (θ) = 4/2. Because of all that we can say: And the other way around: And we also have: Heaps more Trigonometric Identities for you!

2015年11月2日 · Simplify (sec^2 - 1)/sec^2 Ans: sin^2 x Replace sec^2 = 1/(cos^2 x into the expression , we get: (1/(cos^2 x - 1))/(1/(cos^2 x)) = ((1 - cos^2 x)/cos^2 x)((cos^2 x)/1) = Since (1 - cos^2 x) = sin^2x, therefore: (sec^2 x - 1)/sec^2 x = sin^2 x

平方关系：sin²α+cos²α=1。 在三角函数中，csc（余割）和sec（正割）是余弦函数和正弦函数的倒数。 它们与常见的三角函数sin（正弦）、cos（余弦）和tan（正切）之间存在以下关系： csc和sec函数是三角函数领域中常用的倒数函数。 它们在许多数学和物理问题中都有广泛的应用，尤其涉及周期性变化和角度的关系问题。 通过了解csc和sec函数与sin、cos、tan函数之间的关系，我们可以在解决三角函数问题时进行转化和简化，提供更简捷的计算和分析方法。 解答：根 …

rd.second的缩写是2nd.这个数是多少，就写那个数学后面再加这个单调最后的两个字母。 就像twenty-first，只加后面的两个字母即可。
