Question

differentiate
\[ y=x^{-1/2} \]

Answer 1

please show me step by step

Answer 2

i thought the answer would be -1/2...but its not right

Answer 3

y=\[x ^{-1/2}\]
dy/dx=-1/2*\[x ^{-1/2-1}\]
and so u get -.5\[x ^{-3/2}\]

Answer 4

differentiation of \[x ^{n}=n*x ^{n-1}\], so u can follow it up !

Answer 5

mmm im trying to understand how youve got \[-1/2 x ^{-1/2-1)}\]

Answer 6

the -1/2-1

Answer 7

ok, see the general formula i gav. in the formula u can see that n=-1/2, so substitute u'll get answer, got it?

Answer 8

y=x^-1/2
dy/dx= (-1/2)x^(-1/2 - 2/2)
=(-1/2)x^(-3/2)

Answer 9

ok..i get it thanks

Answer 10

ok wc
