When finding the limit of an infinite series, what gives me an indication that the first step in finding the limit is doing partial fraction decomposition?
well the only time partial fractions works is if denominator has degree 2 or greater and can be factored
Is that the only clue? Aren't there times when you won't need to do partial fraction decomposition if the degree of the denominator is greater that one?
lets see, oh right there usually is multiple terms and if the numerator is derivative of denominator then substitution can be used ... but i am thinking of integration
