Check a calculus line you already wrote
Follows a calculus sample already shown on the examples page. Use compute the derivative of x*sin[x] when you want the product rule or the chain rule named, integrate sin(x)cos(x)^2 when the method is substitution or integration by parts, and the rational limit as x approaches 3 when the task is a limit. Enter it with math input and keep your handwritten line beside the screen. That is a suggested lineup with the shown samples, not a worked solution from this page. Was not verified here.
