Time = 0.30 (sec) , antiderivative size = 839, normalized size of antiderivative = 2.47 \[ \int \frac {e^{-3 i \arctan (a+b x)}}{x^4} \, dx=\frac {{\left (-2 i \, a^{2} + 51 \, a + 52 i\right )} b^{4} x^{4} + {\left (-2 i \, a^{3} + 49 \, a^{2} + i \, a + 52\right )} b^{3} x^{3} + 3 \, \sqrt {\frac {{\left (36 \, a^{4} + 216 i \, a^{3} - 456 \, a^{2} - 396 i \, a + 121\right )} b^{6}}{a^{12} - 6 i \, a^{11} - 12 \, a^{10} + 2 i \, a^{9} - 27 \, a^{8} + 36 i \, a^{7} + 36 i \, a^{5} + 27 \, a^{4} + 2 i \, a^{3} + 12 \, a^{2} - 6 i \, a - 1}} {\left ({\left (a^{5} - 3 i \, a^{4} - 2 \, a^{3} - 2 i \, a^{2} - 3 \, a + i\right )} b x^{4} + {\left (a^{6} - 4 i \, a^{5} - 5 \, a^{4} - 5 \, a^{2} + 4 i \, a + 1\right )} x^{3}\right )} \log \left (-\frac {{\left (6 \, a^{2} + 18 i \, a - 11\right )} b^{4} x - \sqrt {b^{2} x^{2} + 2 \, a b x + a^{2} + 1} {\left (6 \, a^{2} + 18 i \, a - 11\right )} b^{3} + {\left (a^{7} - 3 i \, a^{6} - a^{5} - 5 i \, a^{4} - 5 \, a^{3} - i \, a^{2} - 3 \, a + i\right )} \sqrt {\frac {{\left (36 \, a^{4} + 216 i \, a^{3} - 456 \, a^{2} - 396 i \, a + 121\right )} b^{6}}{a^{12} - 6 i \, a^{11} - 12 \, a^{10} + 2 i \, a^{9} - 27 \, a^{8} + 36 i \, a^{7} + 36 i \, a^{5} + 27 \, a^{4} + 2 i \, a^{3} + 12 \, a^{2} - 6 i \, a - 1}}}{{\left (6 \, a^{2} + 18 i \, a - 11\right )} b^{3}}\right ) - 3 \, \sqrt {\frac {{\left (36 \, a^{4} + 216 i \, a^{3} - 456 \, a^{2} - 396 i \, a + 121\right )} b^{6}}{a^{12} - 6 i \, a^{11} - 12 \, a^{10} + 2 i \, a^{9} - 27 \, a^{8} + 36 i \, a^{7} + 36 i \, a^{5} + 27 \, a^{4} + 2 i \, a^{3} + 12 \, a^{2} - 6 i \, a - 1}} {\left ({\left (a^{5} - 3 i \, a^{4} - 2 \, a^{3} - 2 i \, a^{2} - 3 \, a + i\right )} b x^{4} + {\left (a^{6} - 4 i \, a^{5} - 5 \, a^{4} - 5 \, a^{2} + 4 i \, a + 1\right )} x^{3}\right )} \log \left (-\frac {{\left (6 \, a^{2} + 18 i \, a - 11\right )} b^{4} x - \sqrt {b^{2} x^{2} + 2 \, a b x + a^{2} + 1} {\left (6 \, a^{2} + 18 i \, a - 11\right )} b^{3} - {\left (a^{7} - 3 i \, a^{6} - a^{5} - 5 i \, a^{4} - 5 \, a^{3} - i \, a^{2} - 3 \, a + i\right )} \sqrt {\frac {{\left (36 \, a^{4} + 216 i \, a^{3} - 456 \, a^{2} - 396 i \, a + 121\right )} b^{6}}{a^{12} - 6 i \, a^{11} - 12 \, a^{10} + 2 i \, a^{9} - 27 \, a^{8} + 36 i \, a^{7} + 36 i \, a^{5} + 27 \, a^{4} + 2 i \, a^{3} + 12 \, a^{2} - 6 i \, a - 1}}}{{\left (6 \, a^{2} + 18 i \, a - 11\right )} b^{3}}\right ) + {\left ({\left (-2 i \, a^{2} + 51 \, a + 52 i\right )} b^{3} x^{3} - 2 i \, a^{5} + {\left (16 \, a^{2} + 3 i \, a + 19\right )} b^{2} x^{2} - 2 \, a^{4} - 4 i \, a^{3} - 7 \, {\left (a^{3} - i \, a^{2} + a - i\right )} b x - 4 \, a^{2} - 2 i \, a - 2\right )} \sqrt {b^{2} x^{2} + 2 \, a b x + a^{2} + 1}}{6 \, {\left ({\left (a^{5} - 3 i \, a^{4} - 2 \, a^{3} - 2 i \, a^{2} - 3 \, a + i\right )} b x^{4} + {\left (a^{6} - 4 i \, a^{5} - 5 \, a^{4} - 5 \, a^{2} + 4 i \, a + 1\right )} x^{3}\right )}} \]
