OKAY. I AM SOOOOO SORRY, I SWEAR I REALLY AM, I KNOW THERE HAVE BEEN NUMEROUS POSTS ABOUT THIS, BUT HONESTLY ITS NOT WORKING FOR ME AT ALL. I DID A COMBINATION OF THINGS, I WORKED OUT EQUATIONS, I PLUGGED IN, I DARN RIGHT EVEN DID A DANCE TO TRY TO GET THIS BUT ITS NOT WORKING.

I REALLY NEED HELP WITH THE ERROR OF X, IF I DONT GET THAT VALUE, I CANNOT MOVE ON TO GET THE OTHER ERROR VALUES.

I'VE BEEN USING .003m FOR MY ERROR, AND I USED THE ABOVE EQUATION sqrt((.003)^2+(.003)^2) to get .004243 etc... BUT WHEN I PLUG THAT INTO THE EXCEL ITS NOT WORKING. I PLUGGED IN .004, THEN I JUST PLUGGED IN THE WHOLE VALUE, THEN I JUST KEPT TRYING VARIATIONS, BUT NOTHING HAS WORKED. IT REALLY DOESNT MATTER HOW MANY DIGITS I PUT IN, BECAUSE WHEN I PUT IN THE WHOLE THING, IT DOESNT TURN GREEN. UGH.

CAN SOMEONE PLEASE TAKE THE TIME OUT FROM THIS GORGEOUS DAY TO HELP ME OUT. I REALLY APPRECIATE IT. THANKS.
