What is a line integral meaning?
A line integral (sometimes called a path integral) is the integral of some function along a curve. One can integrate a scalar-valued function along a curve, obtaining for example, the mass of a wire from its density. One can also integrate a certain type of vector-valued functions along a curve.

What does dy dx mean?
There are a number of simple rules which can be used to allow us to differentiate many functions easily. If y = some function of x (in other words if y is equal to an expression containing numbers and x’s), then the derivative of y (with respect to x) is written dy/dx, pronounced “dee y by dee x” .
Where did the symbol for the integral come from?
The symbol was based on the ſ ( long s) character and was chosen because Leibniz thought of the integral as an infinite sum of infinitesimal summands . The integral symbol is U+222B ∫ INTEGRAL in Unicode and \\int in LaTeX.
Where does the symbol’int’come from in math?
That is, it’s usually called the “integral symbol”. For its origins: “∫ symbol $\\int$ 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.
What do you call the sign of integration?
As others have already mentioned it is usually called the “integral sign” or the “integral symbol” or just “integral” for short.
Which is the integral symbol in latex and Unicode?
