Frequently Asked Questions about the Scientific Calculator
What functions does this scientific calculator support?
sin, cos, tan, asin, acos, atan, sqrt, cbrt, log (base 10), ln (natural log), exp, abs, floor, ceil, round, plus factorial (!) and exponents (^). Constants: pi and e.
How do I switch between radians and degrees?
Use the toggle in the top-right of the calculator. All trig functions use the selected angle mode.
What does sin(pi/2) equal?
1, when angle mode is radians. In degrees, sin(90) also equals 1.
How do I compute square root or cube root?
Use sqrt(x) for square root and cbrt(x) for cube root. For other roots use x^(1/n), e.g. 27^(1/3) = 3.
Can I use scientific notation?
Yes. Type 1e6 for one million, 2.5e-3 for 0.0025. The result also uses scientific notation for very large or very small numbers.
