Once a word problem has been written as a differential equation, it can be solved using the techniques of the previous section. How many grams of the substance was there. To edit an equation in Word, select the equation field. The Office 365 subscription service typically includes the latest version of Word. Cite this chapter as: West B.H. I would like to make a partial differential equation by using the following notation: dQ/dt (without / but with a real numerator and denomenator). Was this information helpful? The differential equation in first-order can also be written as; y’ = f (x,y) or (d/dx) y = f (x,y) The differential equation is generally used to express a … wikiHow is where trusted research and expert knowledge come together. The general solution of the differential equation is the relation between the variables x and y which is obtained after removing the derivatives (i.e., integration) where the relation contains arbitrary constant to denote the order of an equation.
