What this calculator estimates
Calculate powers, roots, logarithms and trigonometric values from editable numbers and angles.
How to use it
Enter Number x; Exponent y; Angle in degrees. Select Calculate to update the results.
How the calculation works
The calculator uses standard JavaScript mathematical functions for exponents, square roots, base-10 logarithms and degree-based trigonometry.
Worked example: starting scenario
| Number x | 64 |
|---|---|
| Exponent y | 2 |
| Angle in degrees | 30 |
| x raised to y | 4,096 |
|---|---|
| Square root of |x| | 8 |
| Base-10 logarithm of |x| | 1.806179974 |
| Sine of the entered angle | 0.5 |
| Cosine of the entered angle | 0.8660254038 |
Important limitations
Very large powers can exceed browser numeric limits. Trigonometric results are rounded floating-point estimates.
Absolute-value helpers and angle units
The power uses x and y as entered, but the root and common-log helper outputs explicitly use |x|. For x = −9, the helper root is √|−9| = 3; that is not a real square root of −9. The angle input is in degrees: at 90°, sine is approximately 1 and cosine approximately 0. A negative base with a noninteger exponent may have no real-valued result.
