How do you avoid the loss of significance with this expression, sin(x) - tan(x)? I know that subtraction of 2 close real numbers creates large relative error, so how do I restructure this equation in order to get rid of the subtraction sign?
I tried using trig indentities: sin(x) - sin(x)/cos(x) = (sin(x)cos(x) - sin(x))/cos(x), but the subtraction sign does not go away.
