y=tan^(2)(logx^(3)),Find dy/dx...

y=`tan^(2)(logx^(3))`,Find dy/dx

Text Solution

Verified by Experts

Let `y=tan^(2)(logx^(3))`
`therefore (dy)/(dx)=(d)/(dx)[tan(logx^(3))]^(3)`
`=2tan(logx^(3))xx(d)/(dx)[tan(logx^(3))]`
`=2tan(logx^(3))xxsec^(2)(logx^(3))xx(d)/(dx)(logx^(3))`
`=2tan(logx^(3)).sec^(2)(logx^(3))xx3(d)/(dx)(logx)`
`=2tan(logx^(3)).sec^(2)(logx^(3))xx3xx(1)/(x)`
`=(6)/(x)tan(logx^(3)).sec^(2)(logx^(3))`
