About

An integral represents the area under the curve of a function. Indefinite integrals provide a general formula with a constant of integration, while definite integrals compute a numerical value over a specified interval.

How it Works

Enter a valid mathematical function in terms of x. For definite integrals, specify the lower and upper limits. The calculator uses JavaScript math libraries to compute symbolic or numeric integrals.

Advice

Make sure your function is correctly formatted. Use parentheses for grouping, ^ for powers, and Math functions (sin, cos, log, exp). Complex functions may return approximate numeric results.

FAQs

Can I integrate trigonometric functions? Yes, sin, cos, tan, etc. are supported.
Can I integrate exponentials and logarithms? Yes, e^x, ln(x), log(x) are supported.
Are definite integrals exact? Numeric results are approximate but accurate for most practical purposes.
