If like the -1 you add 1 to both sides.would it be the same as or some thing like. x^2 and add ^-2 to both sides.

you have said that everything you do to one side of the equals sign, you do to the other.what if you only want the a and not the a^2.what would you do to the equation.could you also tell me if you move -1 to the LHS of the equation will it be +1.Is there laws for the LHS and the RHS of...

using double angle formula and intergration. i was wanting to know why the the squared eitherside of the equals sign stayed the same.i thought square one side of the equals sign is root the otherside. this is some of my working. cos(2x)=2cos^2_x-1 =cos^2_x-1=sin^2_x...

Thank you ,this is helpfull.Have a good day.may your pc never lag :)

thank you,it would only be just with a quadratic and factoring you have + and a - would this be using the which (a+b)^2 or is this some thing else.

question I am working on at the moment is squares when is (a+b)^2 eather (a+b)(a+b) useing foils law or when (a+b)(a-b) using foils law. im stuck to when you use which one. i think they are when you use quadratic x^2+x+1=0 for the first one or -1 at the end for the second one. i...

The sqeuence of ratios of a fabinacci number F_n+1/F_n on looking at this. F_2/F_1 =1/1 =1 F_3/F_2 =2/1 =2 F_4/F_3 =3/2 =1.5 F_5/F_4 = 5/3 = 1.667 Why would F_n+1 = at F_4 =3 with also F_3=2 I think i understand the squence is fabin accie on the denominater but on the...

Could you tell me how this equation works and how to get to the answer.ive done it before and am still stuck on how 6a^2b^2 is in the middle (a+b)^4 a^4 4a^3b giving the 6A^2B^2 in the middle is it if you have a exponent out side the brackets it works down to ^2 as it would look...

ok sorry I am not sure how to get the symbols on the screen will try again tommorow.

sorry its a composit linear transformation I am looking for.

wow what a day.ive got an a,b,c,d matrix mulitiplyed by an a,b,c,d.matrix and i want to know what combination off a's and b's gives the answer to the 2*2 * 2*2 question. ive read its a1 *a2 b1*b2 c1*c2 d1*d2 is this right as when I've done it i have got a sum that is wrong. The...

so to find a fixed point f(x)=x and the numbers found are at there peak or that they are on the y=x axis.ive got a quadratic equation to work from and asked to find the fixed points.im unsure but thank you for your help.

hi I am working on my exam revision and need to know the fixed point equation.if you could help it would be apreciated. Homework Equations The Attempt at a Solution

im learning so all help is ok.thank you for your help.

ive been working on the seventh root off -128 still have not got it. but now I am trying to work out the factors off z^7+128 do i have to work off z-2 and the quadratic z^2-z-c to get the answers or do you think there is an easyer way. Homework Equations The Attempt at a Solution
