assume X + Y is equal to t therefore 1 + DY by DX is equal to DT by DX
therefore DY by DX is equal to DT by DX -1 equation one becomes
DT by DX minus 1 is equal to sin t + cost therefore Dt by DX is equal to sin t + cost - 1
therefore DT divided by sint+ cost minus 1 is equal to DX
Call tant is equal v
integrate both sides to get the answer
