About the functions available

Alongside the four basic operations, this calculator supports trigonometric functions (sine, cosine, tangent and their inverses), logarithms in base 10 and natural log, powers, roots, and standard constants like π and e. Trigonometric functions are evaluated in radians by default — toggle to degrees mode if your input angles are in degrees, since mixing the two is one of the most common sources of wrong answers on any scientific calculator.
