Compare calculators

Both calculators run independently — change the inputs on either side to compare results.

Limit Calculator

Compute the limit of a rational function (numerator_coeff · x^numerator_power) / (denominator_coeff · x^denominator_power) as x approaches a given value via direct substitution. Returns infinity when the denominator evaluates to zero.
