Is it part of a wider problem? Perhaps there is a clue there.
]]>If so, x²=0.3²-0.2²
x²=0.05
x=√0.05≈0.223

I've been sitting with it for 2 hours now, it just makes me crazy. I mean, it is
a possibility that the mechanical problem that this trig. is derived from is ment
to be solved in an other way, but i wouldn't bet my money on that.
