Find the derivative of y=cos 2x^6....

Find the derivative of `y=cos 2x^6`.

Text Solution

Verified by Experts

The correct Answer is:
b
`veca_(1)[(2hati+3hatj-6hatk)((2hati-3hatj + 6hatk))/7](2hati-3hatj + 6hatk)/7`
`(-41)/49(hati-3hatj + 6hatk)`
`veca_(2) (-41)/49((2hati-3hatj + 6hatk).((-2hati+3hatj+6hatk))/7)`
`xx ((-2hati + 3hatj = 6hatk))/7`
`(-41)/((49)^(2))(-4-9+36) (-2hati+3hatj + 6hatk)`
`943/(49^(2))(2hati -3hatj - 6hatk)`
