The Integral Calculator lets you calculate integrals and antiderivatives of functions online — for free! Our calculator allows you to check your solutions to calculus exercises. It helps you practice by showing you the full working (step by step integration).
To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask for an integral using plain English. integrate x/(x-1) integrate x sin(x^2) integrate x sqrt(1-sqrt(x)) integrate x/(x+1)^3 from 0 to infinity; integrate 1/(cos(x)+2) from 0 to 2pi; integrate x^2 sin y dx dy, x=0 to 1, y=0 to pi
The integral of the secant function was historically one of the first integrals of its type ever evaluated, before most of the development of integral calculus. It is important because it is the vertical coordinate of the Mercator projection, used for marine navigation with constant compass bearing.
The integral calculator allows you to enter your problem and complete the integration to see the result. You can also get a better visual and understanding of the function and area under the curve using our graphing tool.
What we need to do is add together the formulas for the derivatives of the secant and tangent functions. Notice that sec x + tan x appears on both sides of the equation here. If we let u = sec x + tan x and substitute, our equation becomes: u = u · sec x. sec x = . = ln(u).
