    Please help me transpose these formulas.

    Please show workings.


    PLEASE SEE POST BELOW

    Thanks

    v = u + at

    at = v -u

    a = (v -u)/t


    2. a^2 = b^2 = c^2

    I don't know what you mean, perhaps

    b^2 = a^2 = c^2

    3. C = (n-N)/2pi

    n -N = 2C pi

    n = N - 2 C pi

    3. V = pi r^2 /h

    pi r^2 = hV

    r^2= hV/pi

    r = sqrt (hV/pi)

    T = 2 pi/L/g

    = 2pi g/L

    2pi g = LT

    g = LT/2pi



    5. a = b +... NOT CLEAR - Check question

    Thanks a lot terryg752.

    I have posted a much clearer set of questions on my second post.

    Its on the link.

    Thanks.

    1. T = 2 pi sqrt (L/g)

    T/2pi = sqrt (L/g)

    sqrt (L/g) = T/2pi

    L/g = T^2/4pi^2

    g/L = 4pi^2/T^2

    g = 4L pi^2/T^2

    2. a = b + sqrt(b^2 + c^2)

    sqrt(b^2 + c^2) = a - b

    b^2 + c^2 = (a - b)^2

    b^2 + c^2 = a^2 -2ab + b^2

    c^2 = a^2 - 2ab

    c = sqrt (a^2 - 2ab)

    OR c = - sqrt (a^2 - 2ab)

    (2 values of c)
