solve w=va/r^2+a^2 for a

Sagot :

The given equation is

[tex]w=\frac{va}{r^2+a^2}[/tex]

We need to solve it for a

let us cross multiply the two sides

[tex]w(r^2+a^2)=va[/tex]

Divide both sides by w

[tex]r^2+a^2=\frac{va}{w}[/tex]

Subtract r^2 from both sides

[tex]a^2=\frac{va}{w}-r^2[/tex]
