NettetThere's nothing "wrong" with it, but you have to be careful. Some functions that are well-defined over the real numbers become multivalued in the complex numbers. A simpler example: ∫ x2+11 dx = ∫ 2i1 (x−i1 − x+i1) dx ...

Calculus Help: Integral of ∫t^2 e^4t dt or integral of x^2 e^(4x) dx
Nettet6. mar. 2024 · We can manipulate the definite integral as follows: ∫ x4 x √t2 + t dt = ∫ x4 0 √t2 + t − ∫ x 0 √t2 +t dt We have arbitrary chosen the lower limit as 0 wlog (any number will do!). The second integral is is now in the correct form, and we can directly apply the FTOC and write the derivative as: d dx ∫ x 0 √t2 + t dt = √x2 + x NettetSince is constant with respect to , move out of the integral. Step 5. Use to rewrite as . … Nettet7. mar. 2024 · ∫cos4(2t)dt = ∫( cos(4t) +1 2)2 dt Which can be simplified and split up. This simplification will also yield a cos2(4t) term, which can be rewritten by reapplying the same identity as before. See that: cos2(4t) = cos(8t) +1 2 … nemo nm-arst-3p-cy
