I am trying to use the nerdamer library to solve equation. Following is example which works: //multiple roots
var y = nerdamer.solve('x^6+41*x^5+652*x^4+5102*x^3+20581*x^2+40361*x+30030', 'x');
console.log(x4.toString());
But I want to solve with expression containing constant variable calculated already. For example:
var y= nerdamer.solve('x^6+a*x^5+652*x^4+b*x^3+20581*x^2+40361*x+30030', 'x');
where a and b have already been calculated in javascript code above this expression.
How can I do it? is it possible to convert terms into strings and concatenate?
thank you
There are many ways to do this, you could use string concatenation:
var y= nerdamer.solve('x^6+' + a + '*x^5+652*x^4+' + b + '*x^3+20581*x^2+40361*x+30030', 'x');
Or Template literals to allow for variable substitution:
var y= nerdamer.solve(`x^6+${a}*x^5+652*x^4+${b}*x^3+20581*x^2+40361*x+30030`, 'x');
