Hi I've got 2 questions I am not to sure about.
1.Evaluate sinh(1.6), correct to 5 decimal places, using power series methods.
I think i got the answer to this as being 3.16200 by using the series expansion for sinh "x" and putting 1.6 into the equation.
2.Determine the power series for, cos 4t, as far as the term which includes, t6.
Ive no idea what this is about is it using the cosh x series expansion rule or something?
Im using the book "higher engineering mathematics" by John Bird if anyone has any page references or tips.
Thanks
