javascript - How to create a calculus derivative solver using Javascript?

Question

I've been trying to create my own JavaScript program for solving problems in Calculus such as taking the derivative of an equation, but as of yet have not succeeded. I would be greatly appreciative if someone could help me with this.

Answer 1

这样的事情应该这样做

function poly(variable, degree){
 return degree*((variable)^(degree-1));
}

您应该将 n 次多项式存储在 (n+1) 'array' 中并使用 Jquery 每种方法

var result = 0;
$.each(array, function(index, value) {
  result = result + poly(value,index);
});

编辑：如果您不了解 jquery，您可以使用纯 javascript for 循环，for (var i = 0; i < myArray.length; i++) {...}
