make u sub u=1+sqrtx

Hey

#

Do like this

#

Take u=x^2

#

then du=2xdx, which is already given in the integral

#

Sorry I saw the other question!

#

chrome kite make u sub u=1+sqrtx

yeah do that...

#

finally you'll get the answer as 2rootx - 2ln|rootx + 1| + c

#

modulus not needed since rootx is only defined for positive values and zero

#

but wouldn't be a mistake

chrome kite make u sub u=1+sqrtx

What about du tho?

chrome kite Mar 11, 2024, 10:37 AM

#

du=1/2rootx

#

and rootx = u-1

#

from the sub

Ohh i see

#

Ok thank you
