To find the partial fraction decomposition of the expression (t^4 + t^2 + 1) / ((t^2 + 1)(t^2 + 4)^2), follow these steps:
-
Express the numerator as a polynomial in terms of t.
-
Express the denominator as a product of its irreducible factors.
-
Write the partial fraction decomposition as the sum of fractions with unknown constants over each distinct factor of the denominator.
-
Multiply both sides of the equation by the denominator to clear the fractions.
-
Solve for the unknown constants.
After performing these steps, you'll have the partial fraction decomposition of the given expression.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
