You can put this solution on YOUR website!
.

1)   The fragment   " x = arctan/2018 "  is  DEFECTIVE.



2)   In the expression   " cosx-siny/cosy+sinx + cosy-sinx/cosx+siny "

        distribute parentheses to show which part is the numerator and which part is denominator.



Then re-post to the forum.

Please do not post it to me personally.
