How would I do this integral

scarlet vale Nov 21, 2022, 10:47 PM

#

are you integrating with respect to y?

autumn kite Nov 21, 2022, 10:50 PM

#

Yes

scarlet vale Nov 21, 2022, 10:50 PM

#

ah okay

#

do a u substitution for u=6-y

#

rewrite the integral in terms of u, integrate then switch back

#

i can send the full method if you want

autumn kite Nov 21, 2022, 10:51 PM

#

Yes please can you send me the full method

#

So it would be 1/ root u

#

yeah but you also need to change out the dy for du, in this case dy = -du so i took a - out front

#

Another query would u be e^7-3t

scarlet vale Nov 21, 2022, 10:57 PM

#

i would set u=7-3t and take the 5 outside

#
