Quartic Equation Calculator
Quartic Equation Formula: Quartic Equation : ax4 + bx3 + cx2 + dx + e = 0 NOTE : Let p and q be the square root of any 2 non-zero roots. p = sqrt(y1) q = sqrt(y3) r = -g / (8pq) s = b / (4a) x1 = p + q + r - s x2 = p - q - r - s x3 = -p + q - r - s x4 = -p - q + r - s Cubic Equation Formula: 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) y1=(- term1 + r13*math.cos(q3/3) ) y2=(- term1 + r13*math.cos(q3+(2*math.PI)/3) ) y3=(- term1 + r13*math.cos(q3+(4*math.PI)/3) ) This calculator will help you dynamically to calculate the roots of the quartic equation. Calculating roots of quartic equation is made easier.
