Math Solver Calculator

Functions: abs, acos, acosh, asin, asinh, atan, atan2, atanh, cbrt, ceil, cos, cosh, cot, csc, deg, exp, fact, factorial, floor, gcd, hypot, lcm, ln, log, log10, log2, max, mean, min, mod, ncr, npr, pct, pow, rad, rem, root, round, sec, sign, sin, sinh, sqrt, sum, tan, tanh, trunc. Constants: e, phi, pi, tau. Also ! for factorial, ^ for powers, |x| for absolute value.
Applies to sin/cos/tan and their inverses. The CAS mode always works in radians, because the differentiation rules are only valid there.
Applied to the displayed result; the unrounded value is also returned.
Lets the expression use x as a variable, e.g. x^2 + 3x + 2.
Available in the expression as "ans", mirroring the ANS key on a handheld calculator.
Solver mode: the value the expression must take.
Graphing mode: the left edge of the window. Solver mode: the left end of the bracket to search.
Graphing mode: the right edge of the window. Solver mode: the right end of the bracket to search.
Graphing mode: how many evenly spaced x values to sample, endpoints included.

How this is worked out

5 steps
  1. Read as: sin(30) + sqrt(16) with angles in degrees.
  2. 1. sin(30) = 0.5 → 0.5 + sqrt(16)
  3. 2. sqrt(16) = 4 → 0.5 + 4
  4. 3. 0.5 + 4 = 4.5 → 4.5
  5. Result to 10 significant figures: 4.5
Step-by-step workingtable
1. sin(30) = 0.5 → 0.5 + sqrt(16), 2. sqrt(16) = 4 → 0.5 + 4, 3. 0.5 + 4 = 4.5 → 4.5
