Frequently Asked Questions

What is the discriminant?

For a quadratic ax² + bx + c, the discriminant is b² - 4ac. If positive, there are 2 real roots. If zero, there is 1 repeated root. If negative, there are no real roots (2 complex roots).

What is the quadratic formula?

The quadratic formula x = (-b ± √(b²-4ac)) / 2a gives the roots of any quadratic equation ax² + bx + c = 0. It works for all cases — real, repeated, or complex roots.

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.
