Given the equation PV = nRT, rearrange the equation to solve for T.

T = PV/nR

Given the equation Q equals Q sub zero times e to the quantity negative t over R C, rearrange the equation to solve for t.

T equals negative R C times natural log of the quantity q over Q sub zero -RCln(Q/q0)

Given the equation X times tangent theta equals y, rearrange the equation to solve for theta.

Theta equals arctangent of the quantity y over x

Given the equation M g h minus one half m v squared equals zero, rearrange the equation to solve for v.

V equals the square root of the quantity 2 g h V = sqrt(2gh)

Given the equation y = mx + b, rearrange the equation to solve for b.

b = y - mx

Given the equation y = mx + b, rearrange the equation to solve for m.

m = (y-b)/x
