Final answer:
To solve for u in the equation tu=-vsw, you multiply by -1 to get -tu = vsw, and then divide by t to isolate u, resulting in the solution u = (vsw) / t.
Step-by-step explanation:
To solve for u in terms of s, t, v, and w given the equation tu=-vsw, we need to isolate u on one side of the equation.
Firstly, we see that both sides of the equation are multiplied by t and -vsw. To isolate u, we divide both sides of the equation by t:
- Multiply both sides of the given equation by -1 to get rid of the negative sign on the right side: -tu = vsw.
- Divide both sides by t to solve for u: u = (vsw) / t.
Now, u is expressed in terms of the other variables.
