Half-life calculations only showed a significant correlation with survival, if pre-surgery CA 125 levels were used as a baseline. In a survival analysis using the Cox proportional hazards model, stage of disease was the most predictive variable for survival (P = 0.006). The only additional ...
In practical calculations, the sign depends on which quadrant of the plane we are in with our angle. The cos half-angle formula is obtained similarly: cos2(x2)=1+cosx2/cos(x2)=±1+cosx2cos2(2x)=21+cosx/cos(2x)=±21+cosx Lastly, we take the tangent power ...
