eMathHelp Calculators

eMathHelp organizes calculators by course topic, including calculus, matrices, probability, discrete mathematics and linear programming. Its derivative tool takes a function, differentiation count, variable and optional evaluation point, with steps showing the differentiation rules. The documented order limit is ten. Leaving the variable empty requests autodetection; leaving the point empty keeps the derivative unevaluated at a particular point. Its displayed example differentiates x·sin(2x) using product and chain rules to obtain sin(2x)+2x·cos(2x). Separate links lead to implicit and logarithmic differentiation calculators. Set the intended variable explicitly when an expression contains more than one, and distinguish a derivative function from its value at one point.
