Scientific Calculator
Free online scientific calculator with trigonometric, logarithmic, exponential, and statistical functions. Perfect for students, engineers, and professionals.
The scientific calculator provides advanced mathematical functions including trigonometry (sin, cos, tan), logarithms (log, ln), exponentials, factorials, square roots, and constants (π, e). Use it for algebra, geometry, physics calculations, engineering problems, statistics, and academic work.
Switch between DEG (degrees) and RAD (radians) mode when working with trigonometric functions. The result panel shows your pending operation for complex multi-step calculations.
Example
**Example: Physics — Projectile Motion Height**
Calculate the maximum height of a projectile launched at 40° with initial velocity 25 m/s.
Formula: `h = v² × sin²(θ) / (2 × g)` where g = 9.8 m/s²
**Step 1 — Calculate sin(40°):**
Make sure DEG mode is selected. Press `40`, `sin` → displays `0.6428`
**Step 2 — Square it:** Press `xʸ`, enter `2`, press `=` → displays `0.4132`
**Step 3 — Multiply by v² (25² = 625):**
Press `×`, enter `625`, press `=` → displays `258.24`
**Step 4 — Divide by 2g (19.6):**
Press `÷`, enter `19.6`, press `=` → displays `13.18`
**Result:** Maximum height ≈ 13.2 meters. Try changing the angle — 45° gives the maximum range.
