Q ( x ) ≡ 0 ( mod π ) for all x ∈ Z p . This result comes from a similar assertion for the power series attached to the Γ-transform of a p-adic measure which is related to a certain rational function in Z ¯ p 〚 T − 1 〛 .Hae-Sang Sun...
Derivative f’ of the function f(x)=exp x is: f’(x) = exp x for any value of x. Derivative of exponential x Derivative $f’$ of the function $f(x)=\exp x= e^{x}$ is: \(\forall x \in ]-\infty, +\infty[ , f'(x) = \exp x = e^{x}\) Proof/Demonstration \[\b...
Derivative $f’$ of the function $f(x)=\tan x$ is: \(\forall x \neq \frac{\pi}{2}+k\pi, k \in \mathbb{Z}, f'(x) = 1+\tan ^{2} x\) Proof First we have: \((\tan x)' =\lim _{h \rightarrow 0} \dfrac{\tan (x+h) - \tan x }{h}\) Now, let’s simplif...

derivative - the result of mathematical differentiation; the instantaneous change of one quantity relative to another; df(x)/dx derived function, differential, differential coefficient, first derivative curvature - the rate of change (at a point) of the angle between a curve and a tangent to the...
(In other words the derivative of x3is 3x2) So it is simply this: "multiply by power then reduce power by 1" It can also be used in cases like this: Example: What isddx(1/x) ? 1/x is alsox-1 We can use the Power Rule, where n = −1: ...
The standard form to represent the derivative of a function is given below: An infinitesimal change in the variable “x” is denoted by dx. Thus, the derivative of the variable “y” with respect to the variable “x” is given bydy/dx. ...
The mathematical definition of a derivative includes the step of taking a limit of differences of ΔX and ΔY as both approach zero. In the real world, with real data, we can never calculate a true derivative, since we must compute the differences between finite data points, and these ...
