1. What is Constant and Inverse Variation?

Constant variation describes a relationship where the ratio between two variables remains constant (y/x = k), while inverse variation describes a relationship where the product of two variables remains constant (x*y = k). These mathematical relationships are fundamental in algebra and real-world applications.

2. How Does the Calculator Work?

The calculator uses two fundamental variation formulas:

\[ \text{Constant Variation: } k = \frac{y}{x} \] \[ \text{Inverse Variation: } k = x \times y \]

Where:

\( k \) — Constant of variation
\( x \) — First variable value
\( y \) — Second variable value

Explanation: The calculator computes the constant k based on the selected variation type and provided x and y values.

3. Applications of Variation Calculations

Details: Variation calculations are used in physics (Ohm's law, Boyle's law), economics (supply and demand relationships), engineering (stress-strain relationships), and many other fields where proportional relationships exist between variables.

4. Using the Calculator

Tips: Select the variation type (constant or inverse), enter positive values for x and y, and click calculate. The calculator will compute and display the constant k.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between constant and inverse variation?
A: In constant variation, y increases as x increases (direct proportion). In inverse variation, y decreases as x increases (inverse proportion).

Q2: Can the variables be zero?
A: No, both x and y must be positive values. Zero values would make the calculations undefined or meaningless.

Q3: What are some real-world examples of these variations?
A: Constant variation: speed = distance/time. Inverse variation: pressure and volume in gases (Boyle's law).

Q4: How accurate are the calculations?
A: The calculations are mathematically precise based on the input values. The calculator provides results with 4 decimal places for accuracy.

Q5: Can I use negative values?
A: The calculator is designed for positive values only, as variation relationships typically involve positive quantities in real-world applications.
