Question:
Prove that
\[T^{-1} \frac{2}{9} \int_{-\infty}^{\infty} t^{2} \exp \left(-\frac{1}{4} t^{2}ight) d t=\frac{2}{3} \pi^{1 / 2} ho n^{-1 / 2},\]
and
\[T^{-1} \frac{1}{18} \int_{-\infty}^{\infty}|t|^{3} \exp \left(-\frac{1}{4} t^{2}ight) d t=\frac{2}{3} ho n^{-1 / 2},\]
where \(T=\frac{4}{3} ho^{-1} n^{1 / 2}\).

I have completed my graduation in electronics and communication engineering and that's why I have a good knowledge of mathematics (calculus, differential equations, numerical methods,algebra &complex analysis) physics , electronics and communication and basics of electrical technology . In high school I liked chemistry and maths so I have a good knowledge of pre calculus , algebra, Geometry and inorganic chemistry. I am tutoring students offline for past 2 years and I help students to grasp the concepts by relating them to real life scenarios which helps them understand the topic easily whenever possible.
