Edexcel Mathematics: Core C1 6663 17th May 2017 [Exam Discussion]

Any one know how to do Q11 C? Thank You!

C and B are both parallel, so B and C have the same grad. Use the grad from the equation of the tangent u calculated in B and set the = to the derivative of the curve(a). You will then get a quadratic with 2 answers for x, the one you know and another x cordinate. Put this into the equation of curve to get y coordinate to get coordinates

how do you do this question

if i integrate the expression I get,

cx^3 - cx^2 + sqrt(c) + (2x^(3/2))/3 + c

and if i sub everything in, i get a different value of c???

Because you integrated $\sqrt{cx}$ incorrectly.

Hi when i integrate the expression i get f(x)= cx^3 - cx^2 + 2sqrt(c)x^(3/2)/3 + c
when you sub in the coordinate (0,1) all the x terms cancel and youll be left with c=1

Can you guys tell me the hardest core 1 paper in edexcel exam board I'm an aqa exam board student

How do you find an equation of a line perpendicular to another line without being given any coordinates to work with???

I didn't wanna type it so I wrote it out for you.

Difficult to help without being given the full question

Can I see the question?

The line l₁ has equation 3x - 2y + 10 = 0(a) Find the gradient of l₁.1The line l₁ crosses the x-axis at the point A and the y-axis at the point B, as shown in the diagram above.The line l₂ is perpendicular to l₁ and passes through B.(b) Find the equation of l₂

C1 Maths only has 8 chapters...yea do understand - bio and chem are harder...you mean you paid to do as an extra candidate at your school for the exam?

You're told l2 passes through B and l1 passes through B so you can find the point B which u can use as coordinate for l2

How do you find point B though?

who thinks proof for sum of arithmetic series will come up?
