I first found myself fond of the world of mathematics after finding one of my brother's old workbooks on complex analysis. I was so intrigued by it, as I had just finished taking AP Calculus BC in high school. I remember going through different parts of the book and trying to teach myself some of the topics in the book. This and many more like it led me to pursue a double major in math and computer science engineering.
$y^{\prime \prime \prime}+2 y^{\prime \prime}-8 y^{\prime}=0$
$6 z^{m}+7 z^{\prime \prime}-z^{\prime}-2 z=0$
$y^{\prime \prime \prime}+3 y^{\prime \prime}+28 y^{\prime}+26 y=0$
$2 y^{\prime \prime \prime}-y^{\prime \prime}-10 y^{\prime}-7 y=0$
$u^{\prime \prime \prime}-9 u^{\prime \prime}+27 u^{\prime}-27 u=0$
$y^{(4)}+4 y^{\prime \prime \prime}+6 y^{\prime \prime}+4 y^{\prime}+y=0$
