Engineering Calculator

Tap function keys or type an expression, then press = or Enter. Use parentheses: sin(30), sqrt(81), log(100), 2^3, comb(5,2). Choose Degrees for sin(30)=0.5; choose Radians for sin(pi/2)=1. Inverse trig returns the selected angle unit. Percent is entered as /100; mod(a,b) gives a remainder.

Functions: sin, cos, tan, asin, acos, atan, sinh, cosh, tanh, log (base 10), ln, exp, sqrt, cbrt, abs, floor, ceil, round, fact, comb, perm, mod, min, max, pow. Constants: pi, e; ans recalls your last answer. MC clears memory, MR recalls it, M+ adds the last answer, M− subtracts it. C clears the expression and ⌫ deletes one character.
