The method of Hurwitz-Radon Matrices (MHR) enables interpolation of two-dimensional curves using different coefficients [gamma]: polynomial, sinusoidal, cosinusoidal, tangent, cotangent, logarithmic, exponential, arcsin, arccos, arctan
, arcctg or power function , also inverse functions.
u] = 1 this gives for each tree a formula related to the arctan function.
1 Applications: some identities involving the arctan function
So [phi] = [gamma]/2[pi] (arctan
x + b/z - arctan
x - b/z) (4)
realpart := Arcsin(B) else - - use arctan and an accurate approximation to [Alpha] - x if x [is less than or equal to] 1 then Answer.
2])] = arctan (x/ [square root of ([Alpha] + x) ([Alpha] - x))]
Let [theta] = arctan
x/z [member of] (-[pi], [pi]] denote the angle, measured parallel to the y = 0 plane, that a point (x, y, z) makes with the positive z-axis (as described in Section 4).
(1/it) = i/2 In (t - 1)/(t + 1) = i/2 In |(t - 1)/(t + 1)| - 1/2 arg (t - 1)/(t + 1)

gamma] [member of][[theta] - arctan
