fun_deriv: Add derivative

In JohnCoene/funplot: A Powerful Library Built on Top of 'd3.js' Whose Purpose Is to Render Functions With Little Configuration

Description

Add a derivative to the previously added function.

Usage

fun_deriv(p, fun, mouse = FALSE)

Arguments

p	Plot as initialised by funplot.
fun	Derivative, see details.
mouse	Update tip on mouse move.

Details

If mouse is set to true then tangent line is computed whenever the mouse is moved inside the canvas (let x_{0} be the mouse's abscissa then the tangent line to the poin (x_{0},f(x_{1})) is computed whenever the position of the mouse changes).

Examples

funplot() %>%
  fun_add("x^2") %>%
  fun_deriv("2 * x", mouse = TRUE)

funplot() %>%
  fun_add("x * x") %>%
  fun_deriv("2 * x", mouse = TRUE) %>%
  fun_add("x * x * x") %>%
  fun_deriv("3 * x * x", mouse = TRUE)
