3. 余割函数（cosecant function）：余割函数是正弦函数的倒数，表示一个角的余割值。在数学中，余割函数通常用 csc(x) 表示。4. 三角恒等式（trigonometric identity）：三角函数之间存在许多重要的恒等式。其中一个是 tan^2(x) + 1 = sec^2(x)。这个恒等式表明，正切函数的平方加上1等于余割...
Verify the trigonometric identity: secx+tanx=1secx−tanx. Trigonometric Identities: The secant function and the tangent function are related by the following trigonometric identity:1=sec2(x)−tan2(x) . As we see, a trigonometric identity is an equivalence ...
