Applications of Rational Expressions in Science and Engineering

Fractions in the Real World

Rational expressions show up in science and engineering whenever quantities depend on ratios, like speed, density, or resistance.

Key Uses

  • Chemistry: Calculating concentration or reaction rates.
  • Physics: Describing velocity, acceleration, or resistance in circuits.
  • Engineering: Modeling structures or optimizing designs.

Why Are These Useful?

Rational expressions help us break down complex relationships in a way that's easy to calculate and interpret.

Examples

  • Calculating the total resistance in a parallel circuit using \( R_{total} = \frac{1}{\frac{1}{R_1} + \frac{1}{R_2}} \).

  • Finding average speed with \( \frac{total\ distance}{total\ time} \), where time and distance are polynomials.
