If const is FALSE, b is set equal to 0 (zero), and the m-values are adjusted so that y = mx. If const is TRUE or omitted, b is calculated normally. If known_x's is omitted, it is assumed to be the array that is the same size as known_y's.Ī logical value specifying whether to force the constant b to equal 0 The trendline equation and R-squared value are initially displayed as rounded to five digits. If more than one variable is used, known_y's must be a vector (that is, a range with a height of one row or a width of one column). use of a straight line I loved her guidelines and rubric and I have used it. If only one variable is used, known_y's and known_x's can be ranges of any shape, as long as they have equal dimensions. equation of the tangent to the circle at the point P Popular graph types. The array known_x's can include one or more sets of variables. If the array known_y's is in a single row, then each row of known_x's is interpreted as a separate variable.Īn optional set of x-values that you may already know in the relationship y = mx + b If the array known_y's is in a single column, then each column of known_x's is interpreted as a separate variable. The set of y-values you already know in the relationship y = mx + b The TREND function syntax has the following arguments:
