hard quotient rule question

[neat parcel]

ik how to do this, but idk if i differeanted g(x) correctly

[glass timber]

oh god

looks nasty

[neat parcel]

yeh

[glass timber]

lemme see

gimme a few mins

[neat parcel]

k

[scenic hornet]

That’s what I got

[shadow vine]

Don't think you differentiated e^root3x+1 properly there

[scenic hornet]

How would you differentiate it

[shadow vine]

chain rule so root3x+1 differentiated is 3/2 (3x+1)^-1/2 then multiply it by e^root3x+1

[glass timber]

uhh i got

6cos3x/ e^rt3x+1 - 3sin3x/rt(3x+1)

i think it'll be easier with product rule ima try that

[neat parcel]

thats the mark scheme

mad difficult

[scenic hornet]

Bro I’m so stupid

Yeah I differentiated it wron

My fault bruh

[shadow vine]

this primrose kitten person is delusional thinking youd be able to cancel out the (3x+1)^-1/2 just like that

especially for 4 marks

[glass timber]

idk man im getting some crazy answers

[shadow vine]

where the fuck did they get the -2root3 from?

[scenic hornet]

F’(x)?

Oh I didn’t have to simplify

[glass timber]

@scenic hornet yea i got that

bro whered the 2rt3 come from

got tan 3x = 2

[scenic hornet]

Bro how did they get -2rt3 😂😂😂

[opal thistle]

any luck on this one? i'm stumpewd

[misty heart]

Imma try

[misty heart]

Yes but I’ll start next yr

Actually when we finish a-level I believe we have a bit of kinematics and the whole of hypothesis testing left

[glass timber]

primrose papers are shit

[wary moat]

Agreed
