About Scientific Calculator

Getting a strange answer from sine or cosine is nearly always a degrees-versus-radians mismatch. School geometry uses degrees; most programming and physics work uses radians.

Log without a subscript means base ten here, and ln is the natural logarithm to base e. Both are provided separately so you never have to convert between them by hand.

Frequently asked questions

What is the difference between log and ln?
Log is base ten and ln is the natural logarithm, base e.
Does it handle brackets?
