\(\tan\theta=\dfrac{y}{x}\) 显然当\(P\)在第一象限即\(\theta\)为第一象限角时,三角函数的定义与之前相同,但是在平面直角坐标系中定义三角函数就使得其可以不受直角三角形的限制,扩展到任意象限角。 显然对于不同象限的角,\(\sin,\cos,\tan\)的值的正负是不同的: ...

因为sec(θ)sec(θ)的导数为sec(θ)tan(θ)sec(θ)tan(θ),所以sec(θ)tan(θ)sec(θ)tan(θ)的积分为sec(θ)sec(θ)。 sec(θ)+C+∫−4eθdθsec(θ)+C+∫-4eθdθ 由于−4-4对于θθ是常数,所以将−4-4移到积分外。
