why have you started the third topic with the same question??
keep all the questions in one topic!!!!
Remember that you also know the distance between roots (this is what you wrote in another post
maybe this will help
sorry, i dont get it :-(
maybe i'm just to tired :-)
when ax^2 + 0x + 185 what?
hi guys
Do you have any idea where I could find some worksheets (printouts) on propositional calculus - high school?
thanks gamesh.
i'm also looking for some websites with basic and intermidiate problems on mathematical
logic
I am looking for some good websites on mathematical logic (high school level).
Thanks for your help
used for identities (trigonometry) to indicate that something is always true - in trigonometry true for any angle for example.
[f(x)/g(x)]' = (f'(x)*g(x) - f(x)*g'(x))/[g(x)]^2 = (0*x - 1*1)/x^2 = -1/x^2
3. (3x^2-5)/x^2
1. Denominator: (x+4)(x+9)
high school (last three years of HS)
also looking for some good books on trigonometry
hi guys
could you please recommend some books for calculus and geometry
thanks
y = (5 - x)/3
gradient = -1/3
equation of a straight line: y = ax + b where a is a gradient.
btw, you can solve it for p. it is a quadratic equation in terms of p
terms of algebraic expression:
here we have three terms:
10p2
-2p
-1
(1/ln2)*2^x +C
in other words:
(2^x)/lna
i don't know what nationalities you have there but it's 4th house
i don't think it's possible to predict when there will be a prime number. but might be wrong :-(
berthold the chances are much less than 2000000.
i'm not sure how they distribute(divide) the prizes but i'm sure that by buying all possible combination you won't win more than you spent.
to simplify means to divide denominator and denominator by the same number :-)
7% of 9% = 7/100 of 9/100 = 7/100 * 9/100 = 63/10000
i don't get this step:
x^6 + 30x - 1 = 0
Let x^3 = y, then;
y^2 + 30y - 1 = 0
why do you have 30y if y = x^3?
step 5. there you should have absolute value.
thanks guys for quick replies.
