WebLet's apply the derivative operator to both sides of this equation. On the left-hand side, right over here, we get dy/dx is equal to-- now here on the right hand side, we're going to … Webkubleeka. 3 years ago. The solution to a differential equation will be a function, not just a number. You're looking for a function, y (x), whose derivative is -x/y at every x in the domain, not just at some particular x. The derivative of y=√ (10x) is 5/√ (10x)=5/y, which is not the same function as -x/y, so √ (10x) is not a solution to ...
