    Power series when variable is very large

    Homework Statement Find first three non zero terms in series expansion for ln(1+e^-z) when z is very large Homework Equations The Attempt at a Solution I've got as far as ln(1+e^(-1/z)*e^((1/z)(z^(2) - 1)) not sure where to go from here

    Series expansion of logarithmic function

    Homework Statement Find first three non zero terms in series expansion where the argument of funstion is small ln(5+p) Homework Equations The Attempt at a Solution The only way I could think how to do this is by saying ln(5+p) = ln(1+(4+p)) and expanding to (4+p)-...

    what do you mean inclusive angle

    Sin cosine rule

    it still doesn't make any sense, if the triangles are seprate then their area is exactly the same surely, using the sine rule you can find the angle C, then you could find A as you know the two other angles meaning there's only one possible answer for the area

    Sin cosine rule

    who said that the sides were the same length? AB=5 and AC=3.2, who said they were the same? and to symbolipoint, that is the whole question which is why it makes no sense

    Sin cosine rule

    soine cosine rule I have a question for you, I came across this question while revising for my exam on monday if anyone can answer this I'll be very impressed. Two different trangles ABC have AB=5cm, AC=3.2cm and angle ABC=35degrees calculate the difference between their areas.
