Step one, click the Sheet 3 tab in the lower left corner of the screen, and then start writing t

Formula Input Tips:1. Multiply the number with the symbol, you do not have to enter the multiplication sign manually ("*").2. The following help visualize the calculation: a. Use the Math toolbar to enter and use the TAB key appropriately; B. Reasonable use of the space bar.3. When you enter the open root, you can use the shortcut key "\" key, enter the absolute value symbol, the shortcut key can be shift+\

function from Matlab to verify: 1 CoV (mysample) Does the data we calculate be the same?Update: Suddenly discovered today, the original covariance matrix can also be computed, first let the sample matrix center, that is, each dimension minus the mean of the dimension, so that the average value of each dimension is 0, and then directly with the new sample matrix by its transpose, and then divided by (N-1). In fact, this method is also from the previous

Today, a user wrote an email to me about the formula in the list calculation column when reading the SharePoint Portal Server 2003 deep guide, the book only states that "the calculated value formula also supports many functions. Readers can refer to the SharePoint help documentation for a deeper understanding." So the netizen asked me which functions can be used

Polygon Area Calculation Formula Function polygonArea (points) {var I, j; var area = 0; for (I = 0; I Polygon Area Formula description: We all know the three-point area formula of A (x1, y1), B (x2, y2), and C (x3, y3). | x1 x2 x3 |:S (A, B, C) = | y1 y2 y3 | * 0.5 = [(x1-x3) * (y2-y3)-(x2-x3) * (y1-y3)] * 0.5 P

General MRP calculation formula: Net demand = gross demand + allocated volume + safety stock-plan in transit-actual in transit-available stockGross demand: the demand for inventory, manufacturing, and procurement is not considered, relative to the net demand. If it is an independent demand, then the gross demand = the main production plan demand/(1-The expected product is not enough ). For related requireme

There are 33pf filtering capacitors in the audio line, mainly filtering out MHz RF interference. How can this problem be calculated,Is the 217hz tdd_noise related to the filter capacitor? Or should I filter out series inductor or magnetic beads? 2 * pI * freq = SQRT (1/(L * C ))That is to say, This capacitive resonance point has the smallest impedance.You can check the encapsulation parameters of the resistance and capacitance of Murata.Generally, about 0402 of the encapsulation is about 0.5nh

The chief executive sent an e-mail. Request the BOM to increase the "unit price" and "Total Price". "Unit Price" is filled out by its approval, "Total price" is calculated according to "Unit price" and "quantity". and increase the "total amount", the value is equal to the sum of the total price in the schedule.Sub-tabular format required by the Executive DirectorXiaoming quickly changed the data model, form, and data permissions, and then found that the fluffy asked how to proceed with the autom

quantities are shown on the graph. Then from \ (oz=1\) Start step by step to the length of the line (ZZ ' \) and \ (Z ' t_1\), and then calculate the \ (\tan{q} \), you can get the formula above.
