About This Tool
A full scientific calculator supporting arithmetic, trigonometry, logarithms, powers, roots, and memory. Enter expressions directly or use the buttons. Trig functions respect the DEG/RAD mode.
Supported: sin, cos, tan, asin, acos, atan, log (base 10), ln, sqrt, cbrt, abs · Constants: π, e · Operators: +, -, *, /, ^
How to Use
- Select the angle unit: DEG (degrees) or RAD (radians).
- Click buttons or type expressions directly into the display.
- Press = to evaluate the expression.
- Click a history entry to recall that result.
Use Cases
Students use it for math, physics, and engineering problems. Engineers use it for angle, exponent, and logarithm calculations.
FAQ
- What is the difference between DEG and RAD? — DEG computes trig in degrees (sin(90)=1). RAD uses radians (sin(π/2)=1).
- How do I use the memory buttons? — MC: clear, MR: recall, M+: add current value, M−: subtract current value.
- What is the range for n!? — Only integers 0–20 are supported. 21! exceeds 64-bit floating-point precision.
