Please turn the equation so that it can be read horizontally. Also, please explain what each term in the equation is supposed to represent. Then perhaps we will be able to tell you if it is correct and if it isn't, we will be able to point out where you went wrong. Writing the equations in LaTeX is encouraged and will be of great help.
