4.50 · Rating details · 10 ratings · 1 review This text is one of the first to treat vector calculus using **differential** **forms** in place of vector fields and other outdated techniques. Geared towards students taking courses in multivariable calculus, this innovative book aims to make the subject more readily understandable. Introduction. The term **differential** is used nonrigorously in calculus to refer to an infinitesimal ("infinitely small") change in some varying quantity.For example, if x is a variable, then a change in the value of x is often denoted Δx (pronounced delta x).The **differential** dx represents an infinitely small change in the variable x.The idea of an infinitely small or infinitely slow change is. Web. Web. It is the analog of the auxiliary equation that arises in solving the second order linear **differential** equation with constantcoefficients. Eq. (5) is equivalent to, ap 2 + (b 2 a)p+c= 0, (9) and its solutions are given by, p=p±c 1 2 a a 2 b± (a 2 b) 224 ac . (10) Ifp+=p 2 , the we can conclude that the most general solution to eq. (4) is 3. A **differential** k -**form** can be integrated over an oriented manifold of dimension k. A **differential** 1 -**form** can be thought of as measuring an infinitesimal oriented length, or 1-dimensional oriented density. A **differential** 2 -**form** can be thought of as measuring an infinitesimal oriented area, or 2-dimensional oriented density. And so on. A working knowledge of **differential** **forms** so strongly illuminates the calculus and its developments that it ought not be too long delayed in the curriculum. On the other hand, the systematic treatment of **differential** **forms** requires an apparatus of topology and algebra which is heavy for beginning undergraduates.
