Substituting this into the second equation gives 40 = 5k + 20 40 = 5k+ 20, which implies k = 4 k = 4. Thus, we now have the particular solution for the differential equation: 2 \sqrt { h } = 4t + 20 \implies h = (2t + 10) ^ { 2 } . 2 h = 4t+20 h = (2t +10)2.
WebApr 12, 2024 · First-Order Differential Equations As we saw in a previous example, sometimes even though an equation isn't separable in its original form, it can be factored into a form where it is. Another way you can turn non-separable equations into separable ones is to use substitution methods .
