WebApr 12, 2024 · Ionospheric effective height (IEH), a key factor affecting ionospheric modeling accuracies by dominating mapping errors, is defined as the single-layer height. From previous studies, the fixed IEH model for a global or local area is unreasonable with respect to the dynamic ionosphere. We present a flexible IEH solution based on neural network … The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. ... Not really, look at this general triangle and imagine it is two right-angled triangles sharing the side h: The sine of an angle is the opposite divided by the hypotenuse, so: sin(A) = … See more Well, let's do the calculations for a triangle I prepared earlier: The answers are almost the same!
