This will be evident in the examples below. The fundamental theorem of calculus (FTC) states that the integral of a function over a fixed interval is equal to the difference in the values of the ...

IN the second volume of his large treatise on the integral calculus, Mr. Edwards deals with multiple integrals, gamma functions, Dirichlet integrals, definite integrals in general, contour ...

It will be the relationship between these two fundamental principles of calculus, the derivative and the integral, that will be the subject of the next article.
