differentials

[transcendental]

Hey guys, I got stuck at a maths question on 'Local Linear Approximation : Differentials'. Can anyone help me?

=======================================
The hypotenuse of a right triangle is known to be 10 in exactly, and one of the acute angles is measured to be 30 degrees. with a possible error of (plus minus) 1 degree.

(a) Use differentials to estimate the errors in the sides opposite and adjacent to the measured angle.

(b) Estimate the percentage errors in the sides.

Ahh, sorry, I never read the chaper on differential approximations and I handed back my textbooks (I clocked up 8 in the end :p ) to college. If I think of it, then I'll let you know.

Oh never mind, at least you bother to reply. Thank you.;) :D
