As shown in Figure 15-4, the receiver can be described using a mathematical formula: Y1 = H11*X1 + H12*X2 + ... + H1n*Xn. That is, X1 can be received by Y1, Y2, and ... Yn. To obtain the transmit signal, the receive end needs to solve the equation. Figure 15-4 Mathemati...
Learn what a formula is, how functions can be used in Excel, and the most common functions you should use for your spreadsheets.
I am trying to create a data table with two variables, but when I'm initiating the what-if analysis, the data are coming all wrong.
Linear functions, represented by the formula y=mx+b, where m is the slope and b is the y-intercept, describe relationships with a constant rate of change. This means that for any equal increments in the independent variable (typically x), there's a consistent change in the dependent variab...

Although formula (7) is much more accurate than (6) for this example, it would be nice to know how well (7) performs in general. Theorem 3 The rounding error incurred when using (7) to compute the area of a triangle is at most 11, provided that subtraction is performed with a ...
What kind of equation is -2(x + 4) + 1 = -2x - 7? Which is not a counterexample to the formula 1^2 + 3^2 + 5^2 + + (2n - 1)^2 = n(2n + 1)/3? (a) n = 3 (b) n = 2 (c) n = 1 (d) n = 4 Under what situation would one or more solutions of a ration...
In which equation is y proportional to x with a constant of 2? A. xy = 2 B. y = 2x-5 C. 2x+4y = 0 D. (y-8) = 2(x-4) Decide which value(s) of the constant b that fulfill the following equation. Express the following statement as a formula: M varies directly as x and...
