tan^2x tan^2x等于tanx-x,所以tanx-x的导数是tan^2x。如下所示: 导数(Derivative)是微积分中的重要基础概念。当自变量的增量趋于零时,因变量的增量与自变量的增量之商的极限。一个函数存在导数时,称这个函数可导或者可微分。可导的函数一定连续。不连续的函数一定不可导。导数实质上就是一个求极限的过程,导数的...
Using the chain rule for sec(2x) and tan(2x):dudx=ddx(sec(2x))+ddx(tan(2x))=sec(2x)tan(2x)⋅2+sec2(2x)⋅2This simplifies to:dudx=2sec(2x)tan(2x)+2sec2(2x) Step 4: Substitute back into the derivative formulaNow substituting u and dudx back into the derivative formula:...

Step 1: Define the functionLet f(x)=tan2x. Step 2: Apply the definition of the derivativeThe derivative of f(x) using the first principle is given by:f′(x)=limh→0f(x+h)−f(x)hSubstituting our function into this formula, we have:f′(x)=limh→0tan2(x+h)−tan2xhStep...
Evaluate ∫(tan(2x))3sec2(2x)dx. Indefinite Integration: An indefinite integration of a derivative function will give us the primitive function to the antiderivative of the derivative function. The standard formulas of integration can be applied if the function is in a standard form. If...
From the second derivative (1+x3)()- (2 arctan x)(2 x) (1+x2)2 =(2(1-2xarcax))/((1+x^2)^2) (1+x2)2 i follows that points of inflection occur when 2.x arctan x = 1. By using a graphing utility, you can see tha these points occur when x =±0.765. Finally, ...
1. The derivative of tan(2x) is 2sec²(2x).
Find the derivative. y=tan(arcsinx) Derivative of Composite Function: If we have a composition of trigonometric and inverse trigonometric functions (sayT(I(x))), then its derivative is evaluated by applying the chain rule as shown below. ...
