  2. Machin-like formula - Wikipedia

    en.wikipedia.org/wiki/Machin-like_formula

    If = then ⁡ is 45 degrees or radians. This means that if the real part and complex part are equal then the arctangent will equal π 4 {\textstyle {\frac {\pi }{4}}} . Since the arctangent of one has a very slow convergence rate if we find two complex numbers that when multiplied will result in the same real and imaginary part we will have a ...

  3. Clock angle problem - Wikipedia

    en.wikipedia.org/wiki/Clock_angle_problem

    The angle is typically measured in degrees from the mark of number 12 clockwise. The time is usually based on a 12-hour clock. A method to solve such problems is to consider the rate of change of the angle in degrees per minute. The hour hand of a normal 12-hour analogue clock turns 360° in 12 hours (720 minutes) or 0.5° per minute.

  4. Microsoft Math Solver - Wikipedia

    Machin's formula [4] (for which the derivation is straightforward) is: = ⁡ ⁡ The benefit of the new formula, a variation on the Gregory–Leibniz series (⁠ π / 4 ⁠ = arctan 1), was that it had a significantly increased rate of convergence, which made it a much more practical method of calculation.

    L 1, L 2: longitude of the points; L = L 2 − L 1: difference in longitude of two points; λ: Difference in longitude of the points on the auxiliary sphere; α 1, α 2: forward azimuths at the points; α: forward azimuth of the geodesic at the equator, if it were extended that far; s: ellipsoidal distance between the two points; σ: angular ...

  7. Small-angle approximation - Wikipedia

    en.wikipedia.org/wiki/Small-angle_approximation

    The quantity 206 265 ″ is approximately equal to the number of arcseconds in a circle (1 296 000 ″), divided by 2π, or, the number of arcseconds in 1 radian. The exact formula is = ⁡ (″) and the above approximation follows when tan X is replaced by X.
