Find the derivative of y = 4 tan^-1 3x^4...

Find the derivative of `y = 4 tan^-1 3x^4`.

Text Solution

Verified by Experts

The correct Answer is:
224

`vecp,vecq and vecp xx vecq` are perpendicular to each other. We have,
`(veca.vecp) + ( veca.vecq) vecq`
`+(veca.(vecpxxvecq))(vecpxxvecq) =veca |vecp|^(2)`
`(vecb.vecp) vecp + (vecb.vecq)vecq`
`= (vecb.(vecpxxvecq))(vecpxxvecq) =vecb |vecp|^(2)`
`(vecc.vecp) + (vecc.vecq) vecq)`
`= (vecc.(vecpxxvecq))(vecpxxvecq) =vecc|vecp|^(2)`
Hence, the required distance is `|(veca +vecb +vecc)||vecp|^(2)`
`sqrt(|veca|^(2)+|vecb|^(2)+|vecc|^(2))xx |vecp|^(2)`
` 14 xx 4^(2)= 224`
