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

When Excel establishes a financial report, it is usually necessary to calculate the relevant data, which is where we use the Excel program to facilitate the language. In the calculation of data, you need to establish a formula to achieve, and in the use of the formula, you need to refer to the value of the cell to calculate, then in Excel how to use the

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

Tags: OS AR for SP art amp ad BS size The length of data that can be encrypted using RSA is determined primarily by the size of the key you're using. You appear to be using OAEP, so the maximum length is: keyLength - 2 - 2 * hashLength WhereKeylengthIs the length of the RSA modulus in bytes. You're using a 1024 bit key so: keyLength = 1024 / 8 = 128 And since you're using OAEP with SHA-1 hashLength = 20 So the maximum you can encrypt is: 128 - 2 - 2 * 20 = 86 Which is exactly what your

Calculation Formula of capacitor charge discharge time Set, V0 as the initial voltage value on the capacitor;V1 is the final charged or placed voltage value of the capacitor;VT is the voltage value of the capacitor at t time.Then,Vt = "V0" + (V1-V0) * [1-exp (-T/RC)]Or,T = rc * ln [(V1-V0)/(V1-Vt)] For example, a battery with a voltage of E is charged to a capacitor C with a initial value of 0 through

Tags: wireless communication db MW powerIn wireless communication, often hear such a device how many db, in fact, refers to the power, because the power is linear change, not easy to remember and calculate, then use the DB to represent, the complete unit is dbm, is multiplied.Calculation formulas for dbm and power1. The underlying values need to be remembered and then calculated based on this. Example: 0DBM=1MW,1W=1000MW2.DBM increases by 3, the power increases by 1 time times the need to multip

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.

where P is full, r is monthly, and N is the number of periods.For equal principal and interest, the repayment amount of each month is the same, but the interests are decreasing, the first month is the full one-month interest, the second month is to remove the first month after the principal amount of the remaining one months interest, as follows:Assuming a monthly repayment of X, full m, monthly RA1 = X-m*rA2 = x-(M-A1) *RA3 = x-(M-A1-A2) *r...an = X-(M-A1-...-an-1) *ran+1 = x (because A1 + ...

,The total monthly supply remains unchanged. Equal principal method The largest feature of the same amount of principal method is that the monthly repayment amount is different and shows a decreasing status month by month. It distributes the loan principal equally by the total number of months of repayment, plus the interest of the remaining principal in the previous period, in this way, the monthly repayment amount is formed. Therefore, the amount of the first month of the same amount of
