simplifying 😓😓😓

[ornate patio]

how wld u simplify to get the final answer?

i used the ibp formula

[sullen vector]

You need to make a sub

[round lion]

4^3/2 = (rt4)^3 = 2^3 = 8

[sullen vector]

I would change the limits

@ornate patio

[ornate patio]

u can do both

i checked markscheme

[frigid sorrel]

U sub is easier tho

[ornate patio]

i find ibs easier and i already got to the final part😓 i jsut dont know bow to simplify

[frigid sorrel]

Oh shit you’re the person who posted it

Mb

[ornate patio]

how

[ornate patio]

😭😭

[gray sundial]

cursed

[frigid sorrel]

Just type (4)^3/2 in ur calc

I usually do that for all weird powers to see if i gives me a nice answer

[ornate patio]

it gave me a fraction

idk how to get the surd out

[frigid sorrel]

4^3/2 is 8 though

[ornate patio]

huh

[round lion]

did you integrate correctly

[ornate patio]

😭😭😭 omg im tweaking

[ornate patio]

yeah

wait ill show u

[round lion]

4^3/2 is 8 yes

4^5/2 is 32

cuz square root 4 = 2 then 2^5 = 32

[ornate patio]

let me retry

[sullen vector]

@ornate patio you’re gonna be cooking the paper icl

[ornate patio]

lets be real i cant simplify😭

[round lion]

think simply

and you can simplify

[ornate patio]

and then u get 8/3 and 8/15 idk bow to take the surd out omds

[ornate patio]

how it acc hurts my head 💔💔💔

they both shld have a common factor of 32/15 right

[frigid sorrel]

Yeah

Just sub it all in to ur calc bro😭

[round lion]

no

[ornate patio]

but IT DOENST GIVE A SURD

😭

[round lion]

i dont think it should

[frigid sorrel]

Ur forgetting the lower limit bro

[round lion]

with the upper limit

[ornate patio]

its 0

[frigid sorrel]

You’ve only subbed in 4

[round lion]

how is it 0

[ornate patio]

OH

help

👴 i forgot

gimmie a sec

[round lion]

1/cos

here you go

[frigid sorrel]

1/sin

here you go

[round lion]

cooked

[ornate patio]

how r u not getting 0 for yhe lower lomot

. let me try again

[round lion]

can i see what u got after integrating

[ornate patio]

like w the numbers subbed in

[frigid sorrel]

Show all ur working

[ornate patio]

alr

a sec

need to write in the 0

sorry

my dad called

@frigid sorrel @round lion

[round lion]

(x+2)^1/2 doesnt integrate to 2

oh nvm

[frigid sorrel]

0 limit sub is wrong

[ornate patio]

compare my integration to the ms its the same unless i messed up a sign maybe

[ornate patio]

my calculator wait

[frigid sorrel]

-8/15 * (0+2)^5/2

[ornate patio]

amni doing smth wrong

its 0

😭

[frigid sorrel]

0+2…

[ornate patio]

OH

...

🙄

😭

i didnt notice

-32 surd 2 / 15

wait

I GOT IT

OKAY
