• Two circles are concentric. The tangent to the inner circle forms a chord of 12 cm in the larger circle. Find the area of the “ring” between the two circles. • A rectangle 4 by 3 has six squares passed through a diagonal. Find the number of squares passed through by a diag...
For the 40 randomly sampled test data (marked by circles), each phase predicted by the trained ML model is colored in blue for the SPT phase and orange for the trivial phase. The red dot represents a point where the model incorrectly predicted the phase. Full size image...
The lines Y are graduated by projecting from the centre and the central meridian the points at intervals A on the great circles corresponding to the latitudes, thereby forming the azimuthal curves Z. The distances are given by the equation x = R cosec W tan A. To complete the chart for ...
