Equation Solver - Find Root

This feature allow you to find x of an equation. CalcES can solve many type of equations:

  • Linear Equation: 3x + 7 = 16
  • Quadratic Equation: 2x^2 - 4x - 6 = 0
  • Absolute Value Equation: |2x - 3| = 5
  • Exponential Equation: 2^x = 16
  • Logarithmic Equation: log3 of (x) = 2
  • Trigonometric Equation: Sin(x) = Sqrt(2)/2
  • Rational Equation: (x + 3)/(x - 1) = 4/3
  • Radical Equation: Sqrt(2x + 5) = 3
  • Complex Equation: z^2 + 4 = 0
