The geometrical meaning of the derivative of y = f(x) is the slope of the tangent to the curve y = f(x) at ( x, f(x)). The first principle of differentiation is to compute the derivative of the function using the limits. Let a function of a curve be y = f(x). Let us ...

Example 1:y=(3x)x Step 1: Take the natural log of both sides of the equation and use the law of logarithms to simplify. lny=ln(3x)xTakeln Apply Law 1 of Logarithms lny=xln(3x) Step 2: Differentiate implicitly. Apply the Product & Chain Rules to the right hand side. ...
用implicit differentiation求得:y’ = 1/cos y 精彩部分:进一步转化为:y’ = 1/√[1-(sin y)^2] 而sin y = x,因此,(sin y)^2 = x^2, 解出:y’ = 1/√(1-x^2) 书本内容: 第一,书本对反函数进行了进一步的解释(补充高中知识欠缺的我)。 Theorem 5.6 Reflective property of inverse functi...
Here is a revision list of the standard differential coefficients which you have no doubt used many times before. Copy out the list into your notebook and memorize those with which you are less familiar 鈥 possibly Nos. 4, 6, 10, 11, 12. Here they are: y = f(x) dy/dx 1 xn n...
