I need help with this problem. Table L (feet) 0.5, 1.0, 1.5 T (seconds) 0.78, 1.11, 1.36 T=2 pie L/G squared Solve the formula for G. Not sure how to do this can someone help me please.

    no it is not t2 it is T=2*pie L/G squared my computer does not have the squared sign on it.

    notationwise x squared is x^2

    then i am saying it wrong it is the square root of L/G

    sqrt(L/G) is good :) \[T=2pi\sqrt{\frac{L}{G}}\]

    to under the sqrt part; we have to square; they undo each other

    Yes that is the way my problem is written can you help me solve for G using the table I put in on my first post.

    using the table? prolly. It might mean that you want the primary root.

    \[T=2pi\sqrt{\frac{L}{G}}\] \[\left(T=2pi\sqrt{\frac{L}{G}}\right)^2\] \[T^2=4pi^2\frac{L}{G}\] \[GT^2=4pi^2L\] \[G=\frac{4pi^2L}{T^2}\] \[G=\left(\frac{2pi}{T}\right)^2L\] gotta see if that matches up

    or rather, use the values of T and L to find values for G

    All I want is to solve for G using L(ft) 0.5, 1.0, and 1.5 and T(sec) 0.78, 1.11, and 1.36 can this be done and give me a step by step on how to do it.

    But you are not sure if you are on the right track. If you are then thank you and I will see if it works out. If not on the right track then I will check some where else for the help. Sorry not trying to be rude but this is not easy for me to understand.
