+sinx%2F%281-sinx%29-sinx%2F%281%2Bsinx%29=2+

L.C.D. for the left member is %281-sin+x%29%281%2Bsin+x%29.

sinx%281%2Bsinx%29-sinx%281-sinx%29=2%281-sin+x%29%281%2Bsin+x%29
. skipping a step here .
2sin%5E2%28x%29=2%281-sin%5E2%28x%29%29
2sin%5E2%28x%29=2-2%2Asin%5E2%28x%29
4sin%5E2%28x%29=2
sin%5E2%28x%29=1%2F2
sin%28x%29=%281%2F2%29sqrt%282%29

x corresponds to %283%2Api%29%2F4 and to pi%2F4;
highlight%28x+=+pi%2F4%2B-+2npi%29 or highlight%28x=%283pi%2F4%29%2B-+2npi%29.

The FIRST and very long step might be difficult to read because it may appear wrapped in two lines.
