Scientific Calculator
Full scientific calculator with trig, exponents, logs, parens, and memory.
Quick reference
- Trig functions (sin, cos, tan, sin⁻¹, cos⁻¹, tan⁻¹) interpret their input as degrees or radians — switch with the Deg/Rad toggle.
- x² appends
^2to whatever's currently on screen. xʸ lets you enter a custom exponent. 1/x =^-1. - EXP means "× 10 to the power of" — useful for entering things like 6.022 × 10²³.
- Memory: M+ adds the current result to memory, M− subtracts, MR recalls it. MC clears memory.
- Ans brings back the last equals result so you can chain calculations.
- Unclosed parens are auto-closed when you press =, so you don't have to balance them yourself.
FAQ
What functions does this calculator support?
Sine, cosine, tangent and their inverses, square root, cube root, natural log (ln), base-10 log, exponential (eˣ), factorial (n!), and constants π and e. You can also use parentheses freely.
What's the difference between Deg and Rad mode?
Trig functions interpret their input as either degrees or radians. Use Deg for everyday geometry (sin(90°) = 1) and Rad for calculus (sin(π/2) = 1).
Why doesn't 'e' work as I expect?
On this calculator, 'e' is Euler's constant (≈ 2.718). For scientific notation, use the EXP button which inserts × 10^.
