WPS table can be data calculation, analysis and collation, when the use of some more complex formulas, before many people will find ready-made formula to use, or even make a template for repeated use. For example, the calculation of personal income tax and the extraction of sex from the ID card, date of birth, is a fixed formula, will be downloaded from the Internet other people's files, copy a longer

versa.(3) In addition to the formula method, can also be used to solve the drawing method, at this time to choose the scale, strict mapping;(4) When the value of F1 and F2 is certain, the greater the angle between F1 and F2 (α angle), the smaller the resultant force;(5) The synthesis of the force on the same line, can take the positive direction along the straight line, the direction of the force with the sign, the simplification is algebraic operati

Set Ω to M edge shape (for example), vertices are arranged along the boundary forward, and the coordinates are Create a polygon area vector graph of Ω. A triangle is formed by two vertices adjacent to a polygon, and the area of the triangle is obtained by the outer product of two plane vectors composed of three vertices. Area Formula of Any Polygon The calculation of the polygon formula has no relationshi

Sin cos exp is calculated using the Taylor Formula and mclawin formula. To prevent the power operation index from being too high, it is easy to cause overflow when a large input parameter is calculated. Considering that sin and cos both use 2 * PI as the cycle, therefore, set a threshold value in the function (which can be modified by yourself. Here, 2 * pi is used as the threshold value). When the real par

Eddy's Research II Time Limit: 4000/2000 MS (Java/others) memory limit: 65536/32768 K (Java/Others)Total submission (s): 3122 accepted submission (s): 1137Problem descriptionas is known, Ackermann Function plays an important role in the sphere of Theoretical Computer Science. however, in the other hand, the dramatic fast increasing pace of the function caused the value of Ackermann Function hard to calcuate. Ackermann Function can be defined recursively as follows: Now Eddy gives you two numb

Solution quantity time limit: 1000 MS | memory limit: 65535 kb difficulty: 2 Description A chessboard with N * m is given. The coordinate in the lower left corner is (0, 0), and the coordinate in the upper right corner is (n, m). It is required to go up or down to the right at a time, the total number of solutions. It is a 4*3 board. Input Multiple groups of test data. Enter two integers n, m (0 ≤ n, m ≤ 30) in each group ). Input 0, 0 indicates th

Today, we are doing step 1.15 for the publication of SiCp. We need to use the formula and the angle. Although I can write it, I forgot how to prove it. I found a wonderful proof in mathworld: The Euler's formula is used here. I have issued a log record to prove it, but I found it clever to use points! ; SiCp ex1.15 In radians X, the sine value SiNx can be replaced by X. And there is a constant equation S

A wage calculation formula is usually defined in the wage system. For example, real-time = should be issued-should be deducted and so on. To calculate such an expression, the traditional method is to use a reverse polish expression to parse it. The following describes a simple method for computing. Use RPN. php In the pear library of PHP. Usage: Include 'include/pear/RPN. php ';// $ Expression = "(2 ^ 3) + sin (30 )-(! 4) + (3/4 )";$ Expression = "(2.

Basic mathematical formula 1. Number of Parts X number of parts = Total number of parts = number of parts 2. Multiples of 1 x multiples = multiples of a few values; multiples of 1 = multiples of a certain number of values; multiples of a given number = multiples of 1 3. speed X time = distance between minutes speed = time distance between minutes time = speed 4. unit price × quantity = total price ÷ unit price = Total Quantity ÷ quantity = unit price

/*Key Point: Helen FormulaProblem solving person: lingnichongSolution time: 21:48:47Experience in solving problems: Use of Helen's Formula*/ Triangle time limit: 1000 MS | memory limit: 65535 kb difficulty: 1 Description In mathematics, if we know the coordinates of the three points, we can determine whether these three points can form a triangle. If we can form a triangle, we can also find the area of the triangle. As a college student,
