Answer 2

That is, it's usually called the "integral symbol". For its origins: "∫ symbol is used to denote the integral in mathematics. The notation was introduced by the German mathematician Gottfried Wilhelm Leibniz towards the end of the 17th century.
Calculus, known in its early history as infinitesimal calculus, is a mathematical discipline focused on limits, functions, derivatives, integrals, and infinite series. Isaac Newton and Gottfried Leibniz independently discovered calculus in the mid-17th century.
Unlike the indefinite integral, which representsa function, the definite integral represents a number, and is simply the signed area under the curve of f.
Finding the integral of a function with respect to x means finding the area to the x axis from the curve. The integral is usually called the anti-derivative, because integrating is the reverse process of differentiating. The fundamental theorem of calculus shows that antidifferentiation is the same as integration.
