Question

plz help

diffrentiate
2{cot(x^2)}^1/2

Answer 1

first tell what is differentiation of x^1/2?
and have u studied chain rule?

Answer 2

1/2(x)^1/2

Answer 3

right,so differentiation of cot (x^2)^1/2 will be?.....before applying chain rule..

Answer 4

1/2(cotx2)^1/2

Answer 5

right,now if u know chain rule,what will get multiplied to this??

Answer 6

-sin(x^2)

Answer 7

\[-2x (\csc^2 x^2) / \sqrt{\cot x^2}\] please check if I'm right.

Answer 8

2x afterwards

Answer 9

how sin (x^2) ?? what is d/dx of cot x ?? the 2x part afterwards is correct....

Answer 10

ok

Answer 11

i was doing that mistake only

Answer 12

[-\csc^2 x\]

Answer 13

according to standard formula its - cosec ^2 x

Answer 14

ok thanks now i try it

Answer 15

post the final answer u get,so that we can verify....

Answer 16

ok

Answer 17

-2xcosec^(x)^2/{cot(x^2)}^1/2

Answer 18

yup u are correct :)

Answer 19

i got this answer aim was right but in ncert answer is -2\[\sqrt{2} x/\sin(x)^2\sqrt{\sin2x^2}\]
