Integral Calculus Formulas Math
An anti derivative of f x is a function fx such that f x f x.
Integral calculus formulas math. Area of a square. Add one to the exponent. Then 1 lim i b n a n i f x dx f x x. F x dx f x c.
A s2 1 area of a triangle. A formula useful for solving indefinite integrals is that the integral of x to the nth power is one divided by n 1 times x to the n 1 power all plus a constant term. Math results and formulas. It returns a function of the independent variable.
Divide ab into n subintervals of width x and choose x i from each interval. Of the equation means integral of f x with respect to x. The indefinite integrals represent the family of the given function whose derivatives are f. Integrals definitions definite integral.
They represent taking the antiderivatives of functions. Suppose f x is continuous on ab. 1 int 1dx x c. Dx 1 over n 1 x n 1 c xn dx n 11 xn 1 c unless n 1 unless n 1 e x d x e x c int e x dx e x c ex dx ex c 1 x d x ln x c int 1 over x dx ln x c x1 dx lnx c sin x.
