Looking for a online scientific calculator with trig and log? This free tool gives you sin, cos, tan, log, roots, powers, pi and e — right in your browser. Just enter your numbers and press Calculate — results are instant.
A scientific calculator does the maths a basic calculator cannot: trigonometry (sin, cos, tan), logarithms (log is base 10, ln is natural), square roots, powers (x² and xʸ), pi and e, percentages and reciprocals. Angles are in degrees, as they are in school and most everyday work. You can click the buttons or type directly into the display box, and Enter works like the equals button.
Example: Try these on the keypad: sin(30°), 2^10, √144, log(1000)
sin(30°) = 0.5 · 2^10 = 1,024 · √144 = 12 · log(1000) = 3
Degrees, as used in school and most everyday work. Sin(30°) is 0.5, for example. If you need radians, convert first: radians = degrees × π ÷ 180.
The usual maths order: brackets first, then powers and roots, then multiplication and division, then addition and subtraction. Use brackets when you are unsure.
Yes. Click the display box and type, then press Enter — it works like the equals button. The buttons for xʸ, √, log and the rest are also there if you prefer to click.
1/x gives the reciprocal — 1 divided by the number. xʸ raises a number to a power, so 2 xʸ 10 gives 1,024.
