2017 年广西桂林电子科技大学数学专业英语考研真题 B 卷英译汉 1. (1) positive constant (2) trigonometric function (3) absolute value (4) nonnegative integer

(5)the fifth root of x squared (6) the first derivative 2. Let ( , A x y 1 1 ) be a fixed point on a plane with slope m. Let P(x,y) represent x . Then the slope determined by P and A is x any point on the plane, where 1 equal to m. 3. By comparing (1) with (2) in the foregoing section, we see that the concept of instantaneous velocity is merely an example of the concept of derivative. 4. In many problems it is necessary to select from the collection of all solutions one having a prescribed value at some point.

5. The solution of n simultaneous linear equations in n unknowns is one of the important problems of applied mathematics. Descartes, the inventor of analytic geometry and one of the founders of modern algebraic notation, believed that all problems could ultimately be reduced to the solution of a set of simultaneous linear equations. Although this belief is now known to be untenable, we know that a large group of significant applied problems from many different disciplines are reducible to such equations. Many of the applications, require the solution of a large number of simultaneous linear equations, sometimes in the hundreds. The advent of computers has made the matrix methods effective in the solution of these formidable problems.
