Although the rigors of modern science increasingly require of its practitioners greater and greater mathematical sophistication, today's students are often ill-prepared to meet the challenge. Mathematical Techniques aims to rectify that situation. Aimed at beginning students in the engineering, mathematical, and physical sciences, the book offers a course in essential mathematical methods--such as analytic geometry, vector algebra, complex numbers, matrix operations, differential equations, double integrals, Laplace transforms, and Fourier series, among many others. Throughout, the book omits mathematical pedantry and obscure proofs, and presents summary material clearly. A large number of exercises and worked examples are included. Students taking the road down to careers in engineering, chemistry, mathematics, and physics will welcome this friendly introduction to important mathematical techniques.
