steps for the WPS table using the IF formula: The WPS table uses the IF formula step one, opens the statistical tables, the goods kind different, the valuation method is different, has the car number, the ton number, the kilometer, the cubic meter. WPS table using the IF formula Step two, take "car" as an example, in the P4 cell according to "=if",

the design of activities is difficult to achieve scalability and reusability of the design, adjustment procedures are unavoidable, so that each activity must adjust a lot of code. After preliminary analysis, the program adjustment will involve the display of goods, shopping carts and placing orders, these adjustments almost involve the site of all the display foreground.

In the cells of Excel, we can use formulas. If you want to bulk replace the formulas for Excel cells, you cannot do this by using the normal find and replace feature. You have to use the following. Trick. Look at the following table, for example, the formula in column C is: C1=a1+b1 C2=a2+b2 C3=a3+b3 C4=a4+b4 C5=a5+b5 Now we're going to replace these formulas with the following: c1=sheet2! a1+sheet2! B1 c2=sheet2! a2+sheet2! B2

With the development of network and information technology, the supporting role of network to education is increasing, and the web-based teaching mode of distance education has become the dominant one. If you usually have access to mathematics, you need to use a computer to access information, such as teachers, students. They're going to be very anxious because in the computer can hardly enter the mathematical symbols, integration symbols, braces and so on a series, whether it is from the downlo

In order to facilitate the use of border to do the triangle, omit that tedious thinking triangle facing problem, I made a small formula, divided into two, one is the ordinary triangle, one is for the right angle triangle, the formula is as follows:General article:Direction toward which side is not,Color reverse to compensateRight-angled triangle article:Right angle triangle split on both sides,Which side ha

In the 5th edition of "Numerical Analysis" (Li Qingyang), the fourth chapter of Exercise 8th-(2) requires that the Romberg (Romberg) quadrature formula be used to solve the integral of f (x) =xsinx on the interval [0,2pi], and that the error is less than 10^ (-5). To solve this problem, apply the calculation formula. T0=pi*[f (0) +f (2PI) was present in the first step when calculating the trapezoid

There are several reasons why the MathType minus sign is very short: 1. The Chinese and English input method does not switch. Normally, the MathType is the default English input, the English state of the input minus is the standard format, if replaced by the Chinese may appear a minus sign, so after entering the MathType, you need to switch to the English state, press "ctrl+shift" switch can be. 2.

The formula editor is naturally used to edit formulas that are not very useful in previous versions of Word documents, but from Word 2010, the formula editor has been greatly improved, and the formula is not only adjustable and the font is pretty. When the paper was not found in accordance with either the song body or the italics or Microsoft Ya Black and other

after 300 iterations. It can be seen from the cost curve of two experiments that the cost of experiment 1 decreases rapidly with the increase of training times, but the cost of experiment 2 decreases very slowly at first, and intuitively, the higher the initial error, the slower the convergence. In fact, the reason for the slow training due to the large error is that two-time cost function is used. The formula for the two-time cost function is as fol

In the Excel table, we often use the Excel formula to count some reports or data, then we need to use addition, subtraction, multiplication, division, in the previous we have explained in detail the Excel summation and the difference formula use method. So how do we use formulas to compute the multiplication of some data? How fast and convenient to work out the results? The following Word federation will te

In Excel tables, we often use the Excel formula to count some reports or data, and then we need to use addition, subtraction, multiplication, division, in the previous we have explained in detail the formula for the use of differences. So how do we use formulas to compute the multiplication of some data? How fast and convenient to work out the results? The following small series to teach you step-by-step us

1, thousands of lines of formula replication. Put the cursor in the lower right corner, and when it turns black cross, double-click the left mouse button. 　2. Copy formulas across blank lines.
