\(a=\frac{v}{t}\)                            solve for t

 

\(A=\pi r^2\)                        solve for r

 

\(P=I^2R\)                       solve for I

a = v/t     Multiply both sides of the equation by 't

at = v      Divide both sides by 'a'

t = v/a

 

A=pi r^2     Divide both sides by pi

A/pi = r^2    Sqrt both sides

sqrt(A/pi) = r                                 Do you see how it is done?   Can you do the third one?

Hey you beat me to it...the feature that shows other users who are composing doesn't seem to be working anymore

I think you are correct....can honestly say I have not found ONE SINGLE thing in the 'update' that was a good change.

Lol how about the hearts for points EP?

You gotta at least like them a little x)

Nope.  Posted earlier that I thought the hearts were cheesy and the symbol should be something math-related like # or the pi symbol !   Just not feelin' the heart thingie ....

All "solve for" means is get the variable by itself on one side of the equal sign.

\(a=\frac{v}{t}\)

 

Multiply both sides of the equation by t.

\(ta=v\)

 

Divide both sides of the equation by a.

\(t=\frac{v}{a}\)

Hey! time = velocity / acceleration

 

\(A = \pi r^2\)

 

Divide both sides of the equation by pi.

\(\frac{A}{\pi} = r^2\)

 

Take the + square root of both sides.

\(\sqrt{\frac{A}{\pi}} = r\)

radius = the square root of (area / pi)

 

The third one is exactly the same as the second one just with different letters.
