Hi, Does anybody know how to transpose an equation in the TI NSPIRE program or any program that does this. I dont want it to solve the equation just rearrange it with a different subject. For example to make Q the subject in this equation -

H=((1.85Q^(1/4 )u^(3/4))/((gp/p)^(1/2)))

Any help from anybody would be great

thanks mark

The p's in the denominator cancel and you're left with g alone.

\(\displaystyle H=\frac{1.85Q^{\frac{1}{4}}\cdot u^{\frac{3}{4}}}{g^{\frac{1}{2}}}\)

Multiply both sides by \(\displaystyle g^{\frac{1}{2}}\)

Then, divide by \(\displaystyle 1.85u^{\frac{3}{4}}\)

Then, take the fourth power of both sides and you're done.
