^{2}m/T

^{2}

How is that happen? Can someone please explain it to me? Thanks in advance!

In summary, the conversation is discussing the process of deriving the equation k= 4π2m/T2 from T= 2π√m/k. The steps involved include isolating the square root, squaring both sides, and taking the reciprocal.

[tex]T = 2n \sqrt{\frac{m}{k}}[/tex]

The first step would be to isolate the square root. How do you do that?

If have a square root, [itex]y= \sqrt{x}[/itex], square both sides: [itex]x= y^2[/itex]

In both cases we are "undoing" what was done by doing the opposite. In "c= ab", b is not isolated because it is multiplied by a. The opposite of "multiply by a" is "divide by a". The opposite of square root is the square.

Probably a typo- you mean [itex](T/2\pi)^2= \left(\sqrt{m/k}\right)^2[/itex]KevinPaul06 said:Okay thanks I think I get it.

T= 2π√m/k

(T/2π)^{2}= √m/k

T^{2}/4π^{2}= m/k

T^{2}/4π^{2}m = 1/k , then reciprocal both sides.
