About This Scientific Calculator
This calculator supports the full range of functions found on a physical scientific calculator: trigonometry (sine, cosine, tangent and their inverses), logarithms (natural and base-10), powers and roots, and factorial — with a toggle for degree or radian angle mode. You can either click the buttons or type a full expression directly, including function calls like sin(45) and implicit multiplication like 2pi or 3sin(45).
