Harmonic Wave Equation Calculator is a physics/math calculator used to find the displacement of a given point along the wave, the position of that point, the time point, wave velocity, wavelength, amplitude, or initial phase of the wave quickly and easily. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A harmonic of such a wave is a wave with a frequency that is a positive integer multiple of the frequency of the original wave, known as the fundamental frequency. The original wave is also called the 1st harmonic; the following harmonics are known as higher harmonics. Formula: y = A * sin[(2π / λ) * (x - vt) + Φ] where: y - displacement of a given point along the wave x - position of that point (its distance from the source) t - time point v - wave velocity λ - wavelength A - amplitude Φ - initial phase of the wave Thank you for your support, and feel free to visit nitrio.com for more apps for your iOS devices.

The factors of a number are all the integers that you can evenly divide into that number. The Greatest Common Factor (GCF) is the greatest integer that divides exactly into two or more numbers with no remainder. The Greatest Common Factor is used to simplify fractions. To simplify a fraction, you can divide the numerator and denominator of the fraction by the GCF of the numerator and denominator. Factors, the Greatest Common Factor, and simplifying fractions go hand-in-hand. Use this app to get the factors of a number, get the Greatest Common Factor of two or more numbers, and to simplify fractions.
