Find the derivative of `y = 2 ln (3x^2 − 1)`

Answer

`a to p; q`

Explanation

Projection of `vecalpha + betahatj " on" sqrt3hati+hatj " is" sqrt3`
`|alphahati + betahatj.((sqrt3hati+hatj)/2)|=sqrt3`
` Rightarrow sqrt3 alpha + beta = +- 2 sqrt3`
` Rightarrow sqrt3alpha+((alpha-2)/sqrt3)=+-2sqrt3`
` Rightarrow 3 alpha + alpha-2 = +-6`
` 4alpha =8,m -4`
` Rightarrow alpha 2,-1`
