```							wow dude!! wow. this ques was tough as hell. and the solution is beyond big to be posted here! but i will give you the basic ideas, albeit i must warn you that this ques is the definition of LENGTHY af.so..... immediately after looking at the ques, what do you realise?? well, we observe that in order to prove S^2(a^2 + x^2)= 1 (where S= sintheta and costheta=C), we basically need to eliminate b and y from the given set of eqns!. since b and y are only 2 variables and we are provided with 3 eqns, this must be possible at least in theory. so we try our luck at this approach.one slight problem that we might encounter is that the deg of b and y is 2. so we shall first find out b from 3rd eqn in terms of y and other variables, then multiply both sides by b to obtain a b^2 in linear terms of b. we then substitute this value of b^2 in the second eqn.repeat the above steps for y^2.note above that after doing all of these steps we shall obtain two brand new eqns, with just a slight problem that in both of them there would b terms of b*y. so we again need to substitute the value of by from the third eqn in these two eqns to finally obtaiin a truly linear eqn in b and y.once you are done with all this, you will be left with two eqns in b and y. simply eliminate b from these eqns and simplify.you will obtain(y+xc)(a^2S^2+x^2S^2 – 1)=0from which the result follows!!kindly approve :) literally took me eternity to write the entire ans …....
