Scientific Functions Explained
- sin / cos / tan — trigonometry, computed in degrees.
- log / ln — logarithm base 10 and natural log base e.
- xʸ, x², √ — powers and roots.
- π, e — insert constants. Ans — recall last answer.
Frequently Asked Questions
How do I compute 2 to the power of 10?
Type 2, press xʸ, type 10, press equals → 1024.
Why does sin(30) give 0.5?
Because the calculator works in degrees — the sine of 30 degrees is exactly 0.5.
Can I use parentheses?
Yes — press the ( and ) buttons or type them on your keyboard to group expressions.
Does it work offline?
Yes. All math happens in your browser, so the calculator works even without an internet connection.
Practical Example
A few classic operations:
- 2¹⁰ → type 2, press xʸ, type 10 → 1024
- sin(30°) → 0.5 (in degree mode)
- √144 → 12
- ln(e³) ≈ 3
What Your Results Mean
- Trigonometric results — depend on whether the calculator is in degree or radian mode.
- Powers/roots — exact where possible, otherwise shown to display precision.
- Order of operations — follows standard math precedence with parentheses supported.
