જો \(\int {{x^5}\,{e^{ - {x^2}}}\,dx\, = \,g\,(x)\,{e^{ - {x^2}}} + \,c,} \) તો  \(g(-1)\) મેળવો. (કે જ્યાં  \(C\) સંકલનનો અચળાંક  છે)

  1. A \(-1\)
  2. B \(1\)
  3. C \(-\frac {5}{2}\)
  4. D \(-\frac {1}{2}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(-\frac {5}{2}\)

Step-by-step Solution

Detailed explanation

\(\text { Let } x^{2}=t \quad 2 x d x=d t\) \(\Rightarrow \frac{1}{2} \int t^{2} \cdot e^{-t} d t\) \(=\frac{1}{2}\left[-t^{2} \cdot e^{-t}+\int 2 t \cdot e^{-t}, d t\right]\)…
