#

yes

twilit folio Jun 1, 2024, 10:32 PM

#

Differentiate

#

Set that equal to -1/2

#

Tbh

rose tusk Jun 1, 2024, 10:34 PM

#

but you're already given the derivative

twilit folio Jun 1, 2024, 10:34 PM

#

Ooh

#

U gotta flip and then minus sign

twilit folio Jun 1, 2024, 10:35 PM

#

rose tusk but you're already given the derivative

Also what's part a)

rose tusk Jun 1, 2024, 10:35 PM

#

Idk the question is missing

#

probably wants you to integrate

twilit folio Jun 1, 2024, 10:36 PM

#

Ye ig

twilit folio Jun 1, 2024, 10:36 PM

#

rose tusk Idk the question is missing

Find f(x)

#

Prolly

rose tusk Jun 1, 2024, 10:36 PM

#

yes with the 4,9

twilit folio Jun 1, 2024, 10:38 PM

#

Aight I'll explain properly now was eating mb

#

So at normal the gradient would be

#

-1 × reciprocal of dy/dx

#

So -dx/dy

#

And this will be equal to -1/2

#

Because l is parallel to like 2y +x

twilit folio Jun 1, 2024, 10:39 PM

#

twilit folio Because l is parallel to like 2y +x

Ao it will have the same gradient to this line

#

The gradient of this line is y = -x/2

#

So -1/2

#

rose tusk Jun 1, 2024, 10:42 PM

#

I got x=1.5

woven oriole Jun 1, 2024, 10:42 PM

#

Yoyooy

#

Yh it’s x = 1.5

woven oriole Jun 1, 2024, 10:42 PM

#

twilit folio And this will be equal to -1/2

Is that it?

rose tusk Jun 1, 2024, 10:42 PM

#

do u understand it

woven oriole Jun 1, 2024, 10:42 PM

#

I’m aware about allat that stuff

#

I wanna see where I went wrong

rose tusk Jun 1, 2024, 10:44 PM

#

woven oriole Jun 1, 2024, 10:45 PM

#

2 = 2?

#

Where did the extra 2 come from

#

Hol on ill read this stuff tomorrow my heads hurting from so much math today 😭😭😭

#

I appreciate it tho thank you

rose tusk Jun 1, 2024, 10:46 PM

#

Gradient of the tangent is - 1/ gradient of normal

#

Normal has gradient - 1/2

#

so tangent has gradient 2

#

But we're given the gradient function so just set it equal to 2

#

to find the x coordinate

woven oriole Jun 1, 2024, 10:51 PM

#

Shooot Yhh why didn’t I think of that 🤦‍♂️

#

That’s smart thank you bro

rose tusk Jun 1, 2024, 10:54 PM

#

Dk what ur talking about ibr but send it thru I can try 😭😭

#

I’m still y11 tho so idk if I’ve covered it yet

rose tusk Jun 1, 2024, 11:17 PM

#

Check under maths questions

twilit folio Jun 1, 2024, 11:18 PM

#

rose tusk I got x=1.5

Did u do what I said ?

rose tusk Jun 1, 2024, 11:18 PM

#

not quite

twilit folio Jun 1, 2024, 11:27 PM

#

rose tusk not quite

What u do

rose tusk Jun 1, 2024, 11:28 PM

rose tusk Check under maths questions

Fs

twilit folio Jun 1, 2024, 11:32 PM

#

rose tusk Read my earlier message

So basically u did dy/dx = 2

rose tusk Jun 1, 2024, 11:34 PM

#

yes
