WebA right pseudo-inverse is -1 1 2-1 0 0 . There are no left pseudo-inverses for A. For if B were a left pseudo-inverse of A, A would be a right pseudo-inverse of B, and B has more 3 rows and 2 columns. According to the the text, a matrix with more rows than columns never has a right pseudo-inverse.

There is no missunderstanding if use arccos instead of cos−1 Because cos−1 is also understud as 1 cos = sec which is different Answer link MoominDave Jun 1, 2024 WebJul 23, 2024 · Cos (x) = 0.6 means that x = ArcCos (0.6) = 53.13 degrees. This means that the radius vector in the unit circle is 53.13 degrees measured anticlockwise from the right hand horizontal initial position. Cos (x) = -0.6 This means that the radius vector in the unit circle is in the second or third quadrant. Thus the value of ‘x’ is either 180 ... reshoo music app
