another power series question...(adsbygoogle = window.adsbygoogle || []).push({});

I tried it for awhile but it just got out of hand and the ammount of numbers got unbearable.

Q. The increase in resistance of strip conductors due to eddy currents at power frequencies is given by :

X = yt divided by 2 (sinh yt + sin yt divided by cosh yt - cos yt )

If y = 1.08 and t = 1.3, calculate X, correct to 5 significant figures, using power series.

p.s. i dnt know which font it is to do the mathmatical language style :(

Any help would be greatly appreciated. thanks
