Incircle of a regular polygon

Digits after the decimal point: 2
  • Saturation vapour pressure

    This online calculator computes saturation vapour pressure for given temperature and atmospheric (barometric) pressure

  • Seasonal fluctuations. Seasonal indices. Constant mean method.

    The study of periodic (seasonal) fluctuations. Calculation of average seasonal index by constant mean method.

  • Secant method

    The secant method is a root-finding algorithm that uses a succession of roots of secant lines to better approximate a root of a function f.

  • Second, third and other derivatives

    Evaluates first, second third and other derivatives of a single argument function

  • Shadow length

    Gives a vertical object shadow length for given coordinates and time. Also calculates shadow growth during whole day.

  • Shannon Entropy

    This online calculator computes Shannon entropy for a given event probability table and for a given message
