Definition of the logarithm and a stydy of its graph and properties such as domain, range, asymptotes are presented. Examples with detailed solutions are also included.
Under some reasonable conditions, we prove that solutions for the system with nonlinear right hand sides approach a logarithmic function, logarithmic decay and boundedness as time goes to infinity. Our approach is based on a generalized version of Gronwall-Bellman inequality and appropriate desingular...
Logarithmic conformal field theories (LCFT) arose, by noticing that the independent solutions of the null vector equation governing the behaviour of the four-point function, could coincide in certain cases; giving rise to new independent solutions involving logarithms [1], [2]. Previously this poss...
Armed with this understanding, embark on the journey to compute the function and unveil the secrets of the x-variable. For instance, imagine you're tasked with graphing a logarithmic function, and it yields a y-value of 1,500. Implement this value into the formula as illustrated below: 1,...
• Integral of a Logarithmic Function: The integral of logb(x)logb(x) with respect to x is: ∫logb(x)dx=xlogb(x)−xln(b)+C∫logb(x)dx=xlogb(x)−ln(b)x+C • Logarithmic Inequalities: The Logarithmic functions can be used to solve inequalities. For example, to solve logb(...
If a function f is one-to-one, a formula for its inverse can generally be found as follows: Replace f(x) with y. Interchange x and y. Solve for y. Replace y with f 1(x). Example Determine whether the function f(x) = 3x 2 is one-to-one, and if it is, find a ...

With the addition of an input series resistor, the DC log amp can also function as a voltage-input device. Input voltages are converted to a proportional current though the resistor, using the op amp's virtual ground as the reference. Clearly, op-amp input-referred offset must be minimized...
