2×2 Matrix Calculator
Learning & Education · IT & Communication · Science & LabAdd, subtract or multiply two 2×2 matrices, or find the inverse of A. Enter each cell separately and follow row-by-column arithmetic in the result table.
Open calculator ↗Trigonometry Calculator
Learning & Education · Science & Lab · Design & DrawingEnter an angle in degrees or radians to find six trigonometric functions. Explore a unit-circle diagram and sine/cosine graphs.
Open calculator ↗Logarithm Calculator
Learning & Education · Science & Lab · IT & CommunicationCalculate a real logarithm in any valid base, or raise that base to an exponent. Compare natural, binary and decimal logarithms and inspect the inverse relationship.
Open calculator ↗Complex Number Calculator
Learning & Education · Science & LabAdd, subtract, multiply or divide two complex numbers. Enter real and imaginary parts separately, then inspect magnitude, argument and an equal-scale complex-plane diagram.
Open calculator ↗Vector Calculator
Learning & Education · Science & Lab · Design & DrawingEnter two three-component vectors to calculate their sum, difference, dot product, cross product, magnitudes and angle, with an XY-projection diagram.
Open calculator ↗Work Rate Calculator
Time & Planning · Learning & Education · Science & LabCalculate how long two constant-rate workers, machines or pipes take together. Include an opposing drain and an already-completed fraction, with a progress graph.
Open calculator ↗Weighted Average Calculator
Learning & Education · Money Management · Science & LabEnter paired values and weights to calculate a weighted mean. Inspect normalized weight shares, each contribution and a comparison with the unweighted average.
Open calculator ↗Linear Interpolation Calculator
Learning & Education · Science & Lab · Design & DrawingEnter two known points and a target x or y. Calculate the other coordinate, view the straight-line model and clearly distinguish interpolation from extrapolation.
