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.

What most people love first about PyCalc is that they can see and edit their entire calculation all at once. It's a simple idea but it makes a huge difference in the kinds of calculations people end up doing on mobile. But that just scratches the surface of PyCalc's features and capabilities. The more you learn, the more you'll see how easy it is to do calculations that were always too hard before on mobile. Jump in and learn a truly better way of calculating. Basic features: ● A new and better approach to mobile calculation ● A cleaner interface for complicated calculations than traditional calculators ● Calculate by voice ● A history list keeps track of your previous calculations ● Functions built in for a huge range of applications ● Multiple keyboards optimized for different use cases Advanced features: ● Based on the Python® language, with access to the power of a full Python 3.11.1 interpreter ● Programmable scientific calculator: An editable startup.py script allows you to define your own functions for easy access later ● Streamlined support for matrices and fractions ● Many standard Python packages, such as: math, statistics, random, sympy, mpmath, fractions, decimal and datetime ● Basic financial analysis functions: pv(), fv(), npv(), pmt(), etc. ● Built-in support for complex numbers ● Symbolic math via the sympy package ● http/https queries via requests package ● Much, much more...

Verdict

The call

The clearest difference is price: PyCalc at Free against Harmonic Wave Equation Calc's $2.99. PyCalc also leads on update cadence (every 2 weeks vs every 31 months) and ratings volume (15 vs 1). Harmonic Wave Equation Calc's advantage is iOS requirement (13 vs 18.0). On rating, ads, in-app purchases and device support there is nothing between them.
