In a circle which ratio is equivalent to π
The best-known approximations to π dating before the Common Era were accurate to two decimal places; this was improved upon in Chinese mathematics in particular by the mid-first millennium, to an accuracy of seven decimal places. After this, no further progress was made until the late medieval period. WebFeb 16, 2024 · 2. Plug your number into the following formula, and the result will be roughly equal to pi. [12] π=｛arcsin [√ (1 - x²)]+ abs [arcsin x]｝·2. Arcsin refers to the inverse sine in radians. Sqrt is short for square root. Abs is short for absolute value. x^2 refers to an exponent, in this case, x squared.
