Frequently Asked Questions

What is the quadratic formula?

The quadratic formula is x = (-b ± √(b²-4ac)) / (2a). It finds the roots of any equation in the form ax² + bx + c = 0, where a ≠ 0.

What does the discriminant tell you?

If the discriminant (b²-4ac) is positive, there are two distinct real roots. If zero, there is one repeated root. If negative, the roots are complex numbers.

What functions are supported?

This calculator supports sin, cos, tan and their inverses, log (base 10), ln (natural log), exponents (^), square root (sqrt), factorial (!), pi, e, and standard arithmetic operations.

Should I use degrees or radians?

Use degrees for most everyday calculations and geometry problems. Use radians for calculus, physics, and engineering. 180 degrees = pi radians. Most school math uses degrees.
