Math
Scientific Calculator
Evaluate trigonometric, logarithmic, exponential, and absolute functions in a single lightweight panel.
Angle-aware trig, exponentials, logs, and power operations in one panel.
Supported operations
f(x) ∈ {sin, cos, tan, log₁₀, ln, √x, xʸ, eˣ, |x|}Choose one of nine scientific functions. Angle-based modes honor the selected degree/radian setting before applying the function.
How to use
- Pick the desired scientific function from the Operation dropdown.
- If you selected sin, cos, or tan choose whether the input angle uses degrees or radians.
- Enter the primary value (and exponent when using xʸ). The output updates automatically.
Example
Input: Operation = sin(x), Angle mode = Degrees, Value = 45
Output: Output ≈ 0.70710678
FAQ & notes
Why do I see “undefined” for some inputs?
Certain functions, like logarithms of negative numbers or tangent at 90° in degrees, are undefined in real numbers. The calculator flags these cases instead of returning NaN.
Can I switch between degrees and radians?
Yes. When you pick a trig function, an angle mode selector appears so you can flip between degrees and radians instantly.
