How to Calculate Scientific Step-by-Step
- 1Enter numbers with the keypad or your keyboard, then add operators (+, −, ×, ÷) to build an expression.
- 2Use scientific keys for sin, cos, tan, logs, powers, roots, π, e, and factorial. Toggle Inv for inverse trig functions.
- 3Switch Degrees ° vs Radians before evaluating trig expressions so angle units match your problem.
- 4Press = or Enter to compute. Open History to reuse a previous result instantly.
- 5Use MC, MR, M+, M−, and MS to clear, recall, add, subtract, or store values in calculator memory.
Governing formula
result = eval(expression) with θ ∈ {deg, rad}
Evaluates arithmetic and scientific functions (trig, logs, powers, roots, factorial) in your angle mode.
Use the defaults, then adjust one input at a time to see the result update instantly—no sign up.
Variable definitions
- θ
Angle mode
Degrees or radians for trig.
- Inv
Inverse mode
Enables arcsin/arccos/arctan and related inverses.
- Domain errors (e.g. √(−1), log(0)) surface as clear error states.
Scientific Functions Explained
Trigonometric keys evaluate sine, cosine, and tangent of the current angle. Enable Inv for arcsine, arccosine, and arctangent. Always match the Degrees ° or Radians toggle to the unit used in your problem—mixing them is the most common source of trig errors.
Logarithmic work uses ln for the natural log (base e) and log for common log (base 10), with eˣ and 10ˣ as the inverse exponential operations. Powers, roots, factorial, π, and e cover the rest of a standard scientific workflow.
