81) Using integration by parts, we can prove the following asymptotic series e-x2 erf(x) "-J 1- r-;;' Xy7r (x----? oo). 82) On the other hand, if we replace x in the error function by {3x, we have 1 lim - [1 + erf(/3x)] [3-oo 2 ----? 83) where H (x) is a Heaviside function or a unit step function which is defined by H(x) = 1 (for x > 0), H(x) 21 = 0 (for x < 0). 5 Some Special Integrals Calculus At x = 0, it is discontinuous and it is convention to set H(O) = 1/2. Its relationship with the Dirac 8-function is that d~~x) = 8(x).

The divergence of a vector field is the dot product of the del operator \1 and u . 51) 'V· (1/Ju) = 1/J\1· u + (\11/J) · u, \1 x (\1 x u) = \1(\1 · u) - \7 2u. 53) One of the most common operators in engineering and science is the Laplacian operator is 2 \1 w = \1. 55) In engineering mathematics, it is sometimes necessary to express the Laplace equation in other coordinates. In cylindrical polar coordinates (r, , z), we have \7. 57) In spherical polar coordinates (r, 8, ¢), we have \7. 5 Some Important Theorems The Green theorem is an important theorem, especially in fluid dynamics and the finite element analysis.

56 . Their cross product is V =a X b = (1 X 0-0 X (-1),0 X 1-1 X 0,1 X (-1)- 2 X 1) = (0,0, -3), which is a vector pointing in the negative z-axis direction. The vector v is perpendicular to both a and b because a ·V = 1 X 0+1 X 0+0 X ( -3) = 0, and b ·V = 2 X 0 + (-1) X 0+0 X ( -3) = 0. 3 Vector Triple For two vectors, their product can be either a scalar (dot product) or a vector (cross product). 17) or a vector ax (b x c)= (a· c)b- (a· b)c. 2 Vector Algebra Vector Analysis As the dot product of two vectors is the area of a parallelogram, the scalar triple product is the volume of the parallelepiped formed by the three vectors.
