yes, every continuous function is integrable.
A function may have a finite number of discontinuities and still be integrable according to Riemann (i.e., the Riemann integral exists); it may even have a countable infinite number of discontinuities and still be integrable according to Lebesgue. Any function with a finite amount of discontinuities (that satisfies other requirements, such as being bounded) can serve as an example; an example of a specific function would be the function defined as: f(x) = 1, for x < 10 f(x) = 2, otherwise
Yes, a corner is continuous, as long as you don't have to lift your pencil up then it is a continuous function. Continuous functions just have no breaks, gaps, or holes.
They are both continuous, symmetric distribution functions.
The similarities are that they are polynomial functions and therefore continuous and differentiable.A real cubic will has an odd number of roots (and so must have a solution), a quartic has an even number of roots and so may have no solutions.
There is no such thing as a continuous decimal.
That's true. If a function is continuous, it's (Riemman) integrable, but the converse is not true.
No, all functions are not Riemann integrable
In quantum mechanics, acceptable wave functions must be continuous, single-valued, and square-integrable. They must also satisfy the Schrdinger equation and have finite energy.
An antiderivative, F, is normally defined as the indefinite integral of a function f. F is differentiable and its derivative is f.If you do not assume that f is continuous or even integrable, then your definition of antiderivative is required.

Not at all.Y = x2 is a continuous function.
No. Not all functions are continuous. For example, the function f(x) = 1/x is undefined at x = 0.

Yes, all polynomial functions are continuous.
No. There are many common functions which are not discrete but the are not continuous everywhere. For example, 1/x is not continuous at x = 0 (it is not even defined there. Then there are curves with step jumps.

A spectral curve is a mathematical concept used in the study of integrable systems, particularly in the field of integrable models in mathematical physics. It is a curve in the complex plane associated with a particular integrable system, providing information about the system's eigenvalues and other important properties. Spectral curves play a key role in understanding the dynamics and properties of integrable systems.
