The procedure for the partial fraction decomposition is as follows: In a given rational expression, factor the denominator into the linear factors For each factor obtained, write down the partial fraction with variables in the numerator, say x and y To remove the fraction, multiply the whole equation by the denominator factor. /LastChar 196 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 627.2 817.8 766.7 692.2 664.4 743.3 715.6 >> 500 555.6 527.8 391.7 394.4 388.9 555.6 527.8 722.2 527.8 527.8 444.4 500 1000 500 161/minus/periodcentered/multiply/asteriskmath/divide/diamondmath/plusminus/minusplus/circleplus/circleminus Partial Derivatives 1 Functions of two or more variables In many situations a quantity (variable) of interest depends on two or more other quantities (variables), e.g. By implicit differentia-tion with respect to y, 2y + 2z(dzldy) = 0, dzldy = … Indeed L(uh+ up) = Luh+ Lup= 0 + g= g: Thus, in order to nd the general solution of the inhomogeneous equation (1.11), it is enough to nd Remember that the symbol means a finite change in something.
