The coefficients of the differential equation as well as the initial and boundary values are known. In addition the flux through the boundary surface is given. The right hand side is regarded as a function of time. The mentioned problem is reduced to an integral equation. For this, in a ...
We consider the equation \\(u''=f(u)\\) under the conditions \\(u(0)=p\\), \\(u'(0)=0\\), \\(u(\\overline{x}(p))=A\\), \\(u(x)\\in (A,B)\\) for any \\(x\\in (0,\\overline{x}(p))\\), with the unknown function f, where p is a parameter that ...

21.1. Graphical Representation of the Inverse Explain the idea of an inverse function and its graph in your own words. Hint 21.1. Reverse or Mirror Inverse 1) Use general function composition notation to express the statement, “The function g undoes what f does.” as an equation. How do ...
Answer to: A one-to-one function is given. Write an equation for the inverse function. f(x)=2x^3-5 By signing up, you'll get thousands of...
This equation does not describe xx as a function of yy because there are two solutions to this equation for every y>0y>0. The problem with trying to find an inverse function for f(x)=x2f(x)=x2 is that two inputs are sent to the same output for each output y>0y>0. The ...
