Scientific Calculator
Trigonometry, logarithms, powers, factorial, and multi-line expressions. Use Ans for the last result. Angle mode applies to sin, cos, tan, and inverse trig.
Tips: close parentheses after functions (e.g. sin(45)). Use pow(2,8) or 2^8. Constants: pi, e. Comma separates arguments in min, max, pow.
Advanced Scientific Calculator in the Browser
Evaluate trigonometry, logarithms, powers, roots, factorials, and memory operations with a full keypad layout. Toggle degrees or radians for class assignments and engineering estimates.
Expression parsing runs locally—your work stays on-device. Pair with scratch paper for exams that allow calculators following institution rules.
