Best ResponseYou've already chosen the best response.0here we are .. we want to find just piece of line inclination of AB and it must be in polar also. dw:1328171083599:dw so we have to shift AB line and make point A to the origin so it be like that .. i refer it to A' and B' cause its different from original dw:1328171316777:dw This is the Idea .. Lets begin to implement it A(8,80') polar = (1.389,7.878) Cartesian B(11,70') polar = (3.762,10) Cartesian BA = (3.7621.389,107.878)=(2.373,17.878) \[r=\sqrt{2.373^{2}+17.878^{2}}=18.035\] \[\theta 1=270+\tan ^{1} \frac{y}{x}=270+82.4=352.4 \] \[\theta 2= 90+82.4=7.6\] (18.035,352.4') polar and (13.035,7.6) polar Hope I'm right .. regards
