Cubic Equation Calculator
Cubic Equation Formula:
This calculator will help you dynamically to calculate the roots of the cubic equation. Easy to understand and use.discriminant(Δ) = q3 + r2 q = (3c- b2)/9 r = -27d + b(9c-2b2) s = r + math.sqrt(discriminant) t = r - math.sqrt(discriminant) term1 = math.sqrt(3.0)*((-t + s)/2) r13= 2 * math.sqrt(q) x1=(- term1 + r13*math.cos(q3/3) ) x2=(- term1 + r13*math.cos(q3+(2*math.PI)/3) ) x3=(- term1 + r13*math.cos(q3+(4*math.PI)/3) )
