Step 3. Calculate line loss as the square of your current multiplied by your calculated resistance: P(loss)=I²R Using Step 1, you may substitute for I, leaving an equation of: P(loss)=P²R/V² This presents a fundamental axiom of electrical theory: line loss is greatly decreased by an increase in voltage.

To find the slope of a line you must have two points and then you must plug in the two points into the slope formula. The slope formula is m= y2-y1 over x2-x1.

The formula to use is a derivation of the better-known midpoint formula. Letting (m1, m2) represent the given midpoint, (x1, y1) represent the given endpoint, and (x2, y2) represent the unknown endpoint, the formula is: (x2, y2) = (2_m1 – x1, 2_m2 – y1).

There are two methods to calculating the slope of a line in Excel, the first method is to use the gradient formula where slope = (y2-y1)/(x2-x1), while the second method is to make a scatter plot of the data and add a trendline with the equation of the line.

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1), or the change in the y values over the change in the x values. The coordinates of the first point represent x1 and y1. The coordinates of the second points are x2, y2.

To calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. To calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula , .

A regression line is simply a single line that best fits the data (in terms of having the smallest overall distance from the line to the points). Statisticians call this technique for finding the best-fitting line a simple linear regression analysis using the least squares method.

In my book'a section on Young's double-slit experiment, the formula, d=mλsinθ, is given. In this equation d is the distance between two slits, λ is the wavelength of light coming through the slits, and θ is the angle between the central reference to the brightest maximum on the screen opposite the slits.

Trendline equation is a formula that finds a line that best fits the data points. R-squared value measures the trendline reliability - the nearer R2 is to 1, the better the trendline fits the data.

Such formulas can be rather messy. Here is the formula for a linear least squares line, or best fit straight line: (Remember that the equation of a line is y = mx + b, with m = slope and b = y-intercept.)

A net loss appears on the company's bottom line or income statement. Net profit or net loss is calculated using the following formula: Revenues - expenses = net profit or net loss.

Divide the net loss by total sales to derive the extent of the loss. Because there is a net loss, the profit margin calculation is irrelevant. For example, the profit margin calculation is -10 percent if the company reports a loss of $20 million on sales of $200 million ($-20 million divided by $200 million).

The skew lines are L=a+bt,M=c+ds. The distance between two points on L and M is D=(a+bt−c−ds)2=(e+bt−ds)2 where e=a−c. For this to be a minimum, taking partials, we want Ds=Dt=0.
