A derivative is simply a measure of the rate of change. Now, we will derive the derivative of cos x by the first principle of derivatives, that is, the definition of limits. To find the derivative of cos x, we take the limiting value as x approaches x + h. To simplify this, we ...
Mathematically, we can write the derivative of sec^2x as d(sec^2x)/dx = 2 sec2x tanx. We can evaluate the derivative of sec^2x using different methods of differentiation including the chain rule method, product rule and quotient rule of derivatives, and the first principle of derivatives, ...
For differentiating functions in the form of g(x)=u(x)v(x) we use the formula: dg(x)dx=v(x)du(x)dx−u(x)dv(x)dxv(x)2 Differential Calculus in Mathematics deals with finding the derivatives of functions using the first principle, but as the function becomes more and m...

176 Chapter Four USING THE DERIVATIVE 4.1 LOCAL MAXIMA AND MINIMA What Derivatives Tell Us About a Function and its Graph When we graph a function on a computer or calculator, we often see only part of the picture. Infor- mation given by the first and second derivatives can help identify ...
Whenever a limit takes the form of a derivative of a function, we can compute the limit by computing the derivative of the function with known derivative rules. Answer and Explanation:1 The limit limx→0ln(1+x)x can be written as ...
Hello, I am dealing with a function f(x) involving various complicated trig functions. I took the first derivative of the function f(x), which is doable, and set it to zero to find the at which value x the function f(x) would be maximum. However, once I have the derivative of f...
