So, we need to look one step forward: whether the external pressure is constant or variable. If it is constant, we get full work as $-p(V_{\text{final}} - V_{\text{initial}})$; meant for irreversible process. If the external pressure is variable, we obtain the expression from integration.

NettetUsing the product rule of differentiation, we will construct the formula for the Integration of UV. We have two functions, u and v, and that y is the solution to the equation uv. When we use the product rule of differentiation, we will obtain the following results: d/dx (uv) = u (dv/dx) + v (du/dx) After some reorganization of the phrases, we have, Nettet13. apr. 2024 · So it says that u=x. The derivative of that is 1dx. Let’s make dv equal to 5 to the x. Remember if you integrate 5 to the X to get v back, you actually get 5 to the x over the natural logarithm of 5. Since, u = x. du = 1 dx. Similarly, v = (5x) / (ln5) dv = 5x. You can also look at the integration by parts formula to solve that. gfl brown city

"NettetIntegration by parts. The product rule for differentiation says d( uv) = u dv + v du. Integrating both sides of this equation gives uv = ∫ u dv + ∫ v du, or equivalently . This is the formula for integration by parts. It is used to evaluate integrals whose integrand is the product of one function ( u) and the differential of another ( dv). " - Integration of dv/v

Nettet27. apr. 2007 · Yes, for v= y', your differential equation becomes v'= -b-cv 2. That can be written as dv/ (b+cv^2)= -dx. You can simplify a bit by multiplying both sides by b to get dv/ (1+ (c/b)v^2)= -b dx.
