### #94851 Trig Question

Posted by John on 14 March 2007 - 10:41 PM in Mathematics

take the cos over to the other side to get

x+15 = cos^-1(2/3)

x+15 = 48.1897

then solve for x

x = 48.1897 - 15

x = 33.1897

x is in degrees btw

### #94938 circles

Posted by John on 17 March 2007 - 06:40 PM in Mathematics

from there you find the line perpendicular to to the radius

I think you can go on from there.

### #91463 Integration

Posted by John on 02 December 2006 - 07:14 PM in Mathematics

Break the fraction up and use the rules opf indices to simplify and then integrate.

For the second one:

Multiply out the bracket and do the same from there as you did with the first one.

I know there is a simpler way, but i cant remember how to do it.

### #92119 [Quadratic Theory] h/w

Posted by John on 17 December 2006 - 12:27 PM in Problem Questions

For question seven use b

^{2}- 4ac = a negative number, to find the smallest possible integer value for K.

### #91043 Another quadratics question.

Posted by John on 17 November 2006 - 03:04 PM in Problem Questions

Now what you need to do is subsitute x and y for the co-ordinate (0,18).

And then solve for a.

Tell me what you get for your answer and I'll let you know if it is correct.

### #91618 Housing Associations

Posted by John on 05 December 2006 - 05:20 PM in Geography

With the first case, i would assume if they have shares available, anyone, other wise an individual/group.

If you want to know any more I'll just ask my mum, she's on the board for a Housing Association or Local Housing Organisation, one of the two i can't remember lol

### #91588 Housing Associations

Posted by John on 04 December 2006 - 11:51 PM in Geography

This is possible as the organisation is set up specifically to deal with the housing stock, with no interference from the local government.

It also means that the rent you pay is GUARANTEED to go towards the housing stock, whether it be to pay for people to manage it, to fund repairs and regeneration, or to simply keep the tenements and high rise flats clean and tidy in communal areas.

Although repairs and cleansing are normally outsourced to the local government. Which is what happens with GHA managed stock in Glasgow.

But what would be most important to the people, is that they can have a much greater say in the running of their Landlord.

Also, i think this belongs in the Modern Studies forum more than Geography.

### #90163 Trig help

Posted by John on 13 October 2006 - 06:53 PM in Mathematics

*Expand sin(A + B + C) in terms of sin A, sin B, sin C, cos A, cos B, cos C.*

How would i tackle this?

They also ask the same for cos(A + B + C)

Thankies =D

### #91638 Btw......this unit I've been "doing" for the past few weeks....

Posted by John on 05 December 2006 - 10:01 PM in Mathematics

And all you really need to know about Integration from Unit 2 is

Raise the power and divide by that new power.

### #91001 Given the gradient and finding the equation?

Posted by John on 15 November 2006 - 08:56 PM in Mathematics

So do that, you know that dy/dx = 2 so find what dy/dx is and solve it for 2.

So after that you have the x co-ordinate, plug that into the equation of the curve and use the answer from that for the y co-ordinate.

After that use the formula y-b=m(x-a)

Does that make any sense to you?

### #91003 Given the gradient and finding the equation?

Posted by John on 15 November 2006 - 09:12 PM in Mathematics

^{2}-4ac) only tells you the nature of the roots of the quadratic

### #91408 Quadratic question

Posted by John on 30 November 2006 - 09:06 PM in Mathematics

Then solve

3x - 15x + 11= a(x+b) + c

for a.
