$$\mathrm{A}\mathrm{more}\mathrm{difficult}\mathrm{problem}:$$$$\mathrm{What}\mathrm{will}\mathrm{the}\mathrm{postion}\mathrm{of}3\mathrm{D}\mathrm{point}$$$$(x,y,z)\mathrm{in}\mathrm{in}2\mathrm{D}\mathrm{plane}\mathrm{when}\mathrm{viewed}$$$$\mathrm{by}\mathrm{a}\mathrm{point}\mathrm{observer}\mathrm{at}(a,b,c).$$

it's better Tinku tara if you make 2D shape for geometric shape , diagrams ,pie charts , triangle in high resulation edited and data collection like statistics table, more set notation or curve tracing map etc. ..
