How to enter equations

Linear & nonlinear · up to 20 equations

Keep your own order

y + 2FA = 7 or 7 = 2FA + y
Terms and equations can go in any order.

Complex is welcome

x^2 + 1 = 0
Use i or j, or polar notation 10ang(20) (20°).

Go beyond linear

x^2 + y^2 = 25, x*y = 6
Use ^ for powers and * between variables.

Use j10i_1 for j * 10 * i_1. An i or j directly before a number is the imaginary unit; use i_1 for a variable with a numeric subscript. Names like FA, x2, and force_A are single variables. Supported functions: sin, cos, tan, sqrt, exp, log, ln, and abs, with parentheses. Polar notation 10ang(20) means magnitude 10 at 20 degrees. Trigonometric functions use radians; log and ln are natural logarithms. pi and e are constants. Complex logarithms, square roots, and noninteger powers use their principal values. Nonlinear results are numerical candidates; the search may miss roots and does not describe continuous solution families.
