WebStep 1: Enter the linear equation you want to find the slope and y-intercept for into the editor. Correcting measured lengths for slope In this case, the instrument reads 5 so the calibration would suggest a concentration of 4.94 or we want the marble to travel five units of distance so the calibration suggests we enter 4.94 as the input variable for the program controlling the marble launcher. Unlike SLOPE and INTERCEPT, the order does not affect the result of the CORREL function. Let's discuss. Step 2: Put the value in the formula, m = tan in which Ct = the correction for temperature, in m. a = the coefficient of thermal expansion. L = measured distance between two points = 265m. Corrected Distance = [slope distance (hypotenuse) * cosine (slope angle) ] So let's say one were shooting 1200 yards at a 50 degree angle (up or down, I am not sure if there is a difference JBM say's there is but mention of the correction formula in the texts makes no distinction as to what the effects are).
