Let u=1x2u = \frac{1}{x^{2}}u=x21.
The derivative of eue^{u}eu is itself.
Then, apply the chain rule. Multiply by ddx1x2\frac{d}{d x} \frac{1}{x^{2}}dxdx21:
Apply the power rule: 1x2\frac{1}{x^{2}}x21 goes to −2x3- \frac{2}{x^{3}}−x32
The result of the chain rule is:
The answer is:
1 -- 2 x -2*e ------ 3 x
1 -- 2 / 2 \ x 2*|3 + --|*e | 2| \ x / -------------- 4 x
1 -- 2 / 2 9 \ x -4*|6 + -- + --|*e | 4 2| \ x x / -------------------- 5 x
