How to use the Scientific Calculator

  1. Type or use the keypad to enter an expression.
  2. Select degrees or radians mode.
  3. Click = or press Calculate.

Functions: sin, cos, tan, asin, acos, atan, ln, log, sqrt, abs, exp
Constants: pi (π), e

Example

sin(45°) + log(100) = 0.7071 + 2 = 2.7071

Step-by-step calculation

  1. Convert trigonometric input to radians if needed (45° = π/4 radians).
  2. Compute sin(45°) ≈ 0.7071.
  3. Compute log(100) = 2 (base 10).
  4. Add: 0.7071 + 2 = 2.7071.

Real-world uses

  • Engineering and physics calculations.
  • Trigonometry and surveying.
  • Scientific and laboratory work.
  • Mathematics education.

Common mistakes

  • Using degree mode when the expression expects radians (or vice versa).
  • Forgetting parentheses in function calls like sin(45).
  • Using log for natural logarithm (use ln instead; log is base 10).

Frequently asked questions

What is the difference between ln and log?
ln is the natural logarithm (base e). log is the common logarithm (base 10).
Does the calculator support implicit multiplication?
Yes. You can write 2pi or 2(3+4) and the multiplication is inferred.
What does the ! (factorial) operator do?
n! = n × (n−1) × ... × 2 × 1. For example, 5! = 120. Maximum n is 170.
