Can anyone tell me what is the equation for First Order of Newton’s Interpolation? The one of Interpolation I know is Lagrange’s Interpolation such as p(x)= \frac {x-x1}{x0-x1} f(x0) + \frac {x-x0}{x1-x0} f(x1) and so on ... Thanks in advance

What is the answer of \int\frac{1}{cos^2x}d(cos x)?

But, that not the answer I want. I just want to know from what inequality properties that the author can be directly derived the solutions into “1/3 < x < 1/2 or 1/3 < −x < 1/2” form instead “−1/2 < x < 1/2, x < −1/3 or x > 1/3” of mine. Anybody can help me on this?

Hi everyone, I need help again… on “quadratic inequality”. How come the 1/3 < |x| < 1/2 become 1/3 < x < 1/2 or 1/3 < −x < 1/2? And, this is the original problem of above solutions: 1/9 < x^2 < 1/4. I wasn’t able to find the proof from my calculus book because the book says: 1) |x| =...

I wonder if anyone here knows any DERIVATIVE or differentiation book such as “Exercises in Integration” by Claude George, Springer-Verlag. Any advance would be appreciated. Actually, I am looking for MORE techniques, manipulations, etc, on INTEGRATION and DERIVATIVE that could not be found on...

I have 2 questions to ask. Which is “integrand” and the “antiderivative” on the attached image? What is “hyperbolicus” (form of trigonometry identities which include e or exponential)? I am an undergraduate student of engineering, so please tell me the easiest simplest way on this. I...

Hi everyone, I would like to practice Integral problems because I am pretty weak in this field and I have brought a book with a title like DIFFERENTIAL AND INTEGRAL EQUATION which I put thought that the content of the book is about Integral such as standard Calculus book like Varberg, Stewart...

The following 4 of Differential Equations textbooks are the only option of mine: Elementary Differential Equations with Boundary Value Problems, 2E Werner Kohler, Lee Johnson Addison Wesley Differential Equations with Boundary Value Problems, 2E John Polking, Al Boggess, David Arnold...
