How to Use the Explicit Equation Calculator

The Explicit Equation Calculator offers a wide range of mathematical equations, including linear, quadratic, exponential, logarithmic, and polynomial. Here's how to use the tool effectively:

  1. Choose the Equation Type
    Begin by selecting the type of equation you want to solve. The available options are:
    • Linear (y = mx + b)
    • Quadratic (y = ax² + bx + c)
    • Exponential (y = a·bˣ)
    • Logarithmic (y = a·log(x) + b)
    • Polynomial (y = ax³ + bx² + cx + d)
    Once you choose the equation type, the corresponding input fields for the coefficients (a, b, c, d) will appear.
  2. Enter Coefficients
    For each equation type, you need to input the values of the coefficients:
    • a: The coefficient of the highest-degree term in the equation.
    • b: The coefficient of the second-highest-degree term.
    • c and d: These are additional coefficients that appear for quadratic, polynomial, or logarithmic equations.
  3. Set the x Value
    This is where you enter the specific value of x (the independent variable) for which you want to calculate the corresponding y (dependent variable).
  4. Enter the x-Range
    Input the start and end values for x if you want to calculate the y-values over a specific range.
  5. Calculate
    After entering the necessary values, click the Calculate button. The results will display the equation, the y-value at the selected x-value, the slope (rate of change), and other helpful metrics like the range of y-values.
  6. Reset
    If you want to start over with new values, click the Reset button.

Example Calculation: Solving a Quadratic Equation

Let’s say you need to solve the quadratic equation y = 2x² + 3x + 5 for x = 4, and you also want to evaluate the equation for a range of x values from 0 to 10.

  1. Equation Type: Select "Quadratic".
  2. Coefficients:
    • a = 2
    • b = 3
    • c = 5
  3. x Value: 4
  4. x Range: Start = 0, End = 10

After clicking Calculate, the tool would output:

  • Current Equation: y = 2x² + 3x + 5
  • y Value at x = 4: y = 2(4)² + 3(4) + 5 = 2(16) + 12 + 5 = 49
  • Slope at x = 4: 2(2)(4) + 3 = 16 + 3 = 19
  • Range Start y: y = 2(0)² + 3(0) + 5 = 5
  • Range End y: y = 2(10)² + 3(10) + 5 = 200 + 30 + 5 = 235
  • Average y in Range: (5 + 235) / 2 = 120
  • Change in Range (Δy): 235 - 5 = 230

These results give you valuable insights into the behavior of the quadratic equation over the specified range.
