Question

determine dx/dy:
1)y=(sec x+3 ln tanx)^1/4
2)y=lnsqrte^3x(x^2-1)

Answer 1

can you differentiate sec x with respect to x?

Answer 2

i cant

Answer 3

Ok, can you differentiate x^n with respect to x?

Answer 4

n x^(n-1)

Answer 5

That's good can you differntiate lnZ wrt x?

Answer 6

no i cant

Answer 7

can you differentiate lnx wrt x?

Answer 8

honestly i cant differentiate

Answer 9

Ok, differentiating ln tanx wrt x you get cosecx secx
And differentiating secx wrt x you get tanx secx
Can you do it now?
