sec(θ)=32sec(θ)=32,tan(θ)<0tan(θ)<0 The tangent function is negative in the second and fourth quadrants. The secant function is positive in the first and fourth quadrants. The set of solutions forθθare limited to the fourth quadrant since that is the only quadrant found in both...
数学笔记21——三角替换2(tan和sec) tan和sec常用公式 我一直认为三角函数中只有sin和cos是友好的,其它都是变态。现在不得不接触一些变态: 这些变态的相关等式: 等式的证明 这个稍有点麻烦,先要做一些前置工作。 三角替换 示例1 ∫sec4xdx = ? 示例2 ∫tan4xdx = ? 解法1: 解法2: 示例3 ∫sinxs......
x^{2}+a^{2} ,\sqrt{x^{2}+a^{2}} 可以令 x=a \tan \theta \sqrt{x^{2}-a^{2}} 可以令 x=a \sec \theta Question 9: Find \int \frac{\sqrt{x^{2}-9}}{x} d x Solution: 令 x=3 \sec \theta ,则 \frac{d x}{d \theta}=3 \sec \theta \tan \theta ,那么 \...
