To make f the subject of the formula, we need to isolate f on one side of the equation. Let's start by getting rid of the fractions by multiplying both sides of the equation by uv.
u*v*(1/u + 1/v) = uv*(1/f)
v + u = uv/f
Now, let's cross-multiply to eliminate the fraction:
f(v + u) = uv
Next, let's isolate f by dividing both sides of the equation by (v + u):
f = uv / (v + u)
Therefore, f is the subject of the formula.
1/u + 1/v =1/f make f subject of formula
