To convert an inverse tangent (tan-1) to an inverse sine (sin-1), use the identity tan-1(x) = sin-1(x/√(1+x2)). We can understand this formula by looking at a righttrianglewith an angle theta and the opposite sidexand adjacent side 1. ...
For a numberx, the angle between -π/2 radians and π/2 radians whose tangent equalsx; it is the value atxof the inverse of the restriction of the tangent function to the interval between -π/2 and π/2. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003...
We also prove an extension of the Davis-Kahan tan Theta theorem and provide a sharp estimate for the norm of the solution to the Riccati equation. If C is bounded, we prove, in addition, that the solution X is a strict contraction if B satisfies the condition parallel toBparallel to < ...
