Answers to Questions (FAQ)
How to make a formal calculation?
dCode brings you a formal/symbolic calculator which authorizes all calculations and answer an exact result (non-approximate) with the most simplification possible.
Example: Simplification of polynomials with variable: $$ x^2-(x-1)(x+2)+2x = x+2 $$
Example: Computation (addition, subtraction, multiplication, division) with unknowns: $$ a+1+a-2 = 2a-1 $$
These are calculations with variables, but not an equation resolution. dCode has also an equation solver, and other calculus tools such as derivatives, primitives, integrals, etc.

| cos() | cosine |
| sin() | sine |
| tan() or tg() | tangent |
| arcsin() or asin() | arc sine |
| arccos() or acos() | arc cosine |
