Hello All... Could someone please help me with these Q's? 1. If the tangent at P(a,b) on the curve y= 6 / x cuts the y-axis at T(0,3), find the co-ordinates of P. 2. If y = 6x - 11 touches the parabola y = ax^2 + bx + 1 at the point (2,1), find the values of a and b... Thanks for...

Hello All :) Has any one studied the poem 'Before her' by Peter Skrzynecki? My sheet says it is written by him but I'm not sure... If so, could you share your ideas in relations to themes etc... Thanks in advance. :)

Hello All... Can someone please help me with this question? I've tried to do it several times without avail... Q. A plane leaves Adelaide and flies for 875km on a bearing of 056 degrees. It then turns and flies on a bearing of theta for 630km until it is due east of Adelaide. Evaluate...

Hello All... Could someone please see if I've gone through the right process for this question. Q. $Solve for 0^{\circ} \leq \Theta \leq 360^{\circ} 2cos(2{\Theta}) = 1$ So cos(2{\Theta}) = 0.5$ Then because we have 2(theta) in the middle, the range is between 0 and 180. So...

Hello All... Could someone please help me with this question...:) Q. For what value of x does the functions have y = 1/4x -1 have y'= -4/49 __________________________________________________ (Sorry I can't work Latex - This what I tried to do in Latex [tex]$y = lim h$...

Hello All... Sorry to bother you again...:) Could someone please help me with this question? Q. The tangent and normal to the curve y=x^3 at the point U(1,1) meet the y-axis at P and Q respectively. Find their equations, the co-ordinates of points P and Q, and the area of Triangle QUP...

Hello... :) Could someone please see if I'm on the right track for the below question? Q. $If f(x)$ = 2x^2 + 3x,show that f'(0) = 3 by using first principle. $f'(x) = lim h$ -> 0, \frac{f(x+h) - f(x)}{h}\\=\frac{2(x+h)^2 + 3x -(2x^2 + 3x)}{h}\\=\frac{2h(h+2x)}{h} Now, not sure...

Hello All... :) Could someone please help me with this q. I think it should be simple but i'm not getting it. A regular hexagon ABCDEF has sides 5.5cm. Find Angle ADF... I've already have worked out the length of AD is 11cm. Thanks for your help in advance.

And.... how many more topics to you have to go?

Hello All. Could someone please help with the following question? Solve cos^2x=1 Thanks for your help in advance. :)

Hello Everyone... Could someone please help me with.... Q1. Find the exact value of sec 225 deg. Q2. Find the exact value of cosec 300 deg. First thing I tend to do is place it in the difference quadrants... So Q1 would be in Quad 3 (or where T is positive) 45 degrees from 180...

Can someone please help me with Latex. I think I've now download it but ... where do I go from here. Thanks for your help in advance... :)

Hello Everyone. :) I have to complete a Business plan on an existing business or a made up business. Does anyone have any suggestions/comments (including previous experience) ?? Thanks all for your comments in advance. I really appreciate it. :)

Hello... :) Could someone please help me with the following question? Q: Find the equation of the tangent to the curve y=x^2(2x-1)^4 at the point (1,1)... I began by differentiating... Is this right? u= x^2, u'= 2x, v=(2x-1)^4, v' = 8(2x-1)^3.... Which went to 2x(2x-1)^4 + x^2 x...

I'm not sure how to factorise this after differentiating - hopefully I've done this right..... Q:Find the exact gradient of the tangent to the curve y=x(2x+5)^1/2 at the point where x=1... I've differentiated to (2x+5)^1/2 + x(2x+5)^-1/2.... I think the x is wrong? Thanks for your help in...

I really enjoy Doyle's Sherlock Holmes stories... What amazes me - they were written many years ago!! :) Anyone else enjoy these stories?? Wish I could use them as a related text somehow!!

Hello All Does anyone use the abbreviation parm. instead of parallelogram? I believe this was acceptable in previous years and not sure if it still is... I would be glad of comments/ideas in regard to this. :):):)

Hello All... Could you please help me with the following question???? Diagram shown... Given info: AD//BC, AX = DX, Angle ABC= Angle BCD a) Show that Angle ABD = Angle ACD b) Prove Triangle DAB is congruent to Triangle ACD c) Show that AB = DC Thanks heaps in advance, I appreciate your...

Could someone please help me with this question? Differentiate (first express in simplest index form) y=(x+ √x)/x Thanks in advance.... :)

How do you differentiate this using the Product Rule? 4x(3x - 2)^5 I got 4(1 + 5x^2 -10x)(3x - 2)^4... I don't know what I've done wrong... Thanks heaps.
