C1 and C2 DOUBTS HERE!!!!!

[The Golden Girl =D]

question in attached

thanks in advanced

I did face such a Question in Chapter 6 C3 ( I think it's the same one)

I asked my teacher where he got the -1 from and this is what he did :

He substituted (theta = 0  {x = 0} ) in the Equation, in other words:

y = tan (theta -45)
y = tan (0 - 45)
y = tan (-45)
y = -1

Which means it has to intersect with y-axis at that point i.e. ( -1 , 0 )

I hope you got it

                           ...................................................................

another question to bother this thread about is here

for who have C2 book its on page 193 Q 6 in the revision exercise 3

what I don't understand is that the book's answer is 4 and when I did integration of the two parts of my  sketch , one area was -ve and other was +ve so I added them ignoring the -ve sign so...............are these steps right or I've just missed somethnig up cause my anwser was ''9.5''

Thanks in advance  

Here is the Answer from the Solution Bank :

Area = integration sign thingy with base 2 4x³-3x²dx Remember integration sign thingy axⁿdx=(axⁿ⁺¹) /(n+1 )

Anyhoo here it is
 
=[(x⁴/4) - x³]₂⁴  }=> The 4 is supposed to be in the TOP and  2 at the BOTTOM  but it didn't turn out to be perfect so thought of Mentioning it incase any confusion was caused =]
 
=[((4)⁴ /4 )-(4)³)] -[(2)⁴/4) -(2)³) ]

=(64-64) - [(16 /4) -8]
=0-(4-8)
=0-(-4)
=4

When u click on the solutionbank it comes out in a new internet explorer window, ryt?

But then there comes a yellow coloured pop-up on top wich says something like 'Internet explorer has restricted this webpage from running scripts or ActiveX controls that could access yur computer' , ryt?

Click (or right-click) on that yellow pop-up thing and select 'Allow blocked content'. Then there comes a box saying something like 'Are you sure you want to let ActiveX scripts run on your computer?'

Then click yes. The solutionbank then appears. Just try doing this and see if it works.

Umm....i dunno why this happens...but try downloading the C1 and C2 ActiveBooks and then select the SolutionBank icon in it which for me then opens up in a new internet explorer window. Try downloading the Activebooks instead of the SolutionBanks - hop u get it.

If this doesn't work, let me know what doubts u hav in C1 and C2 because i m also sitting for the two modules in jan and i will try my best to help u out. This will help my understandng and urz as well.

Like Sir astarmathsandphysics said, all ActiveBooks r free on freetextbooks.com, downalod them from there. And no, the Activebooks r not different from the textbooks - they r just to make revision easier.

Ohh mention not, do let me know what other doubts u hav soon. Solving now....will let u know later today. Meanwhile, here is the hint for this question from the C1 SolutionBank:

Hint:
Write out the first three or four terms of the calculation to help you work out what is happening.

Sorry, i m unable to copy/paste the actual solution to this question from the SolutionBank, but will understand the answer myself and then explain to u

Take care.
