find the gradient of the tangent at that point
and normal tangent perpendiciular so u can do negative reciprocal thing
surreal temple
and normal tangent perpendiciular so u can do negative reciprocal thing
then u use the y - y1 = m(x-x1) to find the equation of the normal
vast gazelle
Oh
vast gazelle
Alright I’ll try
surreal temple
|| dy/dx = 4x -1
4(1) - 1 = 3
so normal grad is -1/3
y - 4 = -1/3(x-1)
y-4 = -1/3 x + 1/3
y = (-1/3)x + 13/3
to find intersections set both equations to eachother as they both = y
(-1/3)x + 13/3 = 2x^2 - x + 3
collect terms
2x^2 -2/3x -9/3 = 0
solve for x ||
vast gazelle
Which equation are you doing equal to the normal equation
The 2x^2 - x + 3
Like where did it come from
@surreal temple
surreal temple
The 2x^2 - x + 3
thats the equation of the curve bro
vast gazelle
Oh yeah my bad
surreal temple
Lol
vast gazelle
I was looking at another question so I got confused
surreal temple
Zack what other subjects do you do
surreal temple
I was looking at another question so I got confused
Yeah it be like that
surreal temple
Mb
vast gazelle
It’s fine
vast gazelle
Zack what other subjects do you do
Are u about to say I’m gonna fail them because I’m this dumb
vast gazelle
😂
Oh alright
I find the other two super easy
I mean I’m getting A*s in all 3 atm
surreal temple
I mean I’m getting A*s in all 3 atm
Rahhhh
surreal temple
I find the other two super easy
Nice
vast gazelle
But in maths I just have to work a bit harder
vast gazelle
Oh really
surreal temple
Yeah i find chem harder
surreal temple
psychology is easy
in difficulty its like this for me
hardest to easiest
chem, fm, psych, maths
surreal temple
Yeah
vast gazelle
How much harder are you finding it than normal maths
surreal temple
I mean we only just moved from gcse to a level in regular maths so regular is a lot easier
But fm isnt taht bad atm
Its just
Very long.
vast gazelle
Ah
That’s weird how you’ve only just moved to a level content in maths
We started doing it like 3 weeks after we started
surreal temple
That’s weird how you’ve only just moved to a level content in maths
We were doing straight line graphs and quadratics for ages
vast gazelle
Strange
vast gazelle
I love coordinate geometry
surreal temple
Real
surreal temple
So idk why I’m struggling with differentiation
Youll get it eventually 🙏
vast gazelle
Anyway I’m gonna finish off this question
surreal temple
Have fun with that
