Usage

num_int(f, grid, constant = 0)

Arguments

f	A sequence of values of a function
grid	The corresponding x axis
constant	Optional constant to add to the derivative.

Value

The integral between the start of the grid up until the grid.

Examples

x <- seq(from = 0, to = 2 * pi, by = 0.01)
f <- sin(x)

plot(x, -cos(x), type = "l", col = "red")
points(x, int_f, col = "blue")
