## anonymous 5 years ago find the derivative of F(x)=arctan sqrt(3x-1)

1. Vijay

$(1/ 2x * \sqrt{3x-1})$

2. anonymous

i got stuck cuz i got 1/3x*1/2(3x-1)^-1/2

3. anonymous

im confused

4. anonymous

can u break this down to me

5. anonymous

i dont understand how this is the answer

6. anonymous

i got 1/6x sqrt(3x-1)

7. anonymous

i just need to know what step am i missing

8. anonymous

vijay did u type somethin cause im not able to see what is being typed

9. Vijay

u have differentiate inside the bracket, i mean 3x-1

10. Vijay

so, u will 3 above, that 3 will be cut 6

11. Vijay

did u differentiate 3x-1 d(3x-1)/dx = 3

12. anonymous

i dont understand because i thought i was supposed to differentiate sqrt (3x+1) which would be 1/2(3x+1)^-1/2

13. Vijay

yes that that is correct, after this expression, u have to differentiate inside the sqrt .
