Question

Find an equation of the tangent line to the curve at the given point.
y= x^(1/2), (1,1)

Answer 1

So you need to differentiate y=x^(1/2)
have you done that yet?

Answer 2

\[\text{ the tangent line to } f \text{ at } (a,f(a)) \text{ is } y-f(a)=f'(a)(x-a)\]

Answer 3

1/2(x^(1/2)) is the derivitive

Answer 4

Got it, Thank you!

Answer 5

oh you got it ?
you need no more help?

Answer 6

that is
\[y'=\frac{1}{2 x^{\frac{1}{2}}}\]?

Answer 7

Thats the same thing I got, thank you
