If a smooth curve C is given by parametric equations x=x(t),y=y(t)), then the slope of the tangent line of the curve at a point (x(t0),y(t0) is given by y′(t0)x′(t0), and the tangent line to the curve at the point ...
Equation of a tangent line: $$y - b = y' (x - a) $$ where {eq}y' {/eq} is the slope of that curve at the given {eq}x {/eq} - value {eq}(a) {/eq}. Answer and Explanation:1 Given curve: {eq}y = x^2 + 2x - 1 {/eq} ...
根据题意:The equation of the tangent line就是求此点的切线方程,先求过此点切线的斜率:求导得:y'=(1/3)(18 -2x)^(1/3-1)=(1/3)(18 -2x)^(-2/3)=1/[3³√(18 -2x)²]把x=5代入得:y'=1/[3³√(18 -10)²]=1/[3³√64]=1/[3·(4)]=1/12即切线斜率=1/12;y=...

equation of the line tangent 公式我们要找出直线与曲线相切的方程。 首先,我们需要知道切线的定义和性质,然后使用这些性质来找出切线的方程。 假设曲线方程为 y = f(x),切点为 (x0, f(x0))。 切线的斜率等于函数在该点的导数,即 f'(x0)。 所以,切线的方程可以表示为:y - f(x0) = f'(x0) ×...
