Math calculator
Scientific Calculator
Evaluate scientific expressions with trigonometry, logarithms, roots, powers, constants, factorials, and degree or radian modes.
Formula
Scientific expression evaluation
Supports sin, cos, tan, inverse trig, ln, log10, sqrt, powers, factorials, pi, e, and parentheses
In DEG mode, sin(30) + sqrt(144) evaluates to 12.5.
FAQs
Does the scientific calculator support degrees and radians?+
Yes. Use DEG for degree-based trigonometry and RAD for radian-based expressions.
Can I use constants and previous answers?+
Yes. Use pi, e, and Ans in expressions. The Ans key reuses the previous result.
How does the Scientific Calculator calculate the result?+
It uses the Scientific expression evaluation: Supports sin, cos, tan, inverse trig, ln, log10, sqrt, powers, factorials, pi, e, and parentheses. In DEG mode, sin(30) + sqrt(144) evaluates to 12.5.
What information do I need to use the Scientific Calculator?+
Evaluate scientific expressions with trigonometry, logarithms, roots, powers, constants, factorials, and degree or radian modes.
How accurate is the Scientific Calculator?+
Scientific Calculator applies the formula and assumptions shown on this page. Results may be rounded for readability, so verify changing rates, thresholds, medical guidance, or legal rules with the cited source or a qualified professional.
What should I check before using the Scientific Calculator result?+
Check that the units, dates, rates, and assumptions match your situation. Change one input at a time to understand which values have the largest effect on the result.
