Mathematics: Post your doubts here!

[LMGD33]

This question got to everyone. No one ever posted a solution in this thread! If someone could PLEASE solve it, I would be so grateful.
What I would recommend, however, is to draw it on a graph paper, and then use trigonometry.

i can only help with a half answer.. So sorry

actuali may be i typed wrong its 4x/(4+x^2) !! Sorry!!! Thnk u!

My bad!! If I divided by two I should have also multiplied the whole thing by 2 as well >.<
Answer would be 2 ln (4 + x^2)

Honestly, this was the HARDEST paper ever! The threshold for an A was 47/75! How crazy is that?

Exactly. Last three questions were something out of this world.

I can't see any of your photos, including your iteration one. Could you please tell me how would I present my work when they ask to display each iterative value to 4 decimal places?

And can ANYONE find the value of arg z? q 10 ii . It's like it's impossible! http://papers.xtremepapers.com/CIE/...S Level/Mathematics (9709)/9709_w12_qp_32.pdf

Hey can someone please tell me how to find the gradient by dy/dx in the following cases:

1) When the tangent passes through the origin

2) When the tangent is parallel to the y-axis

3) When the tangent is parallel to the x-axis
