When two variables are related in some or the other way and if their ratio remains the same, then they are said to be in direct variation. The unchanged constant value is termed as constant of variation. Use this direct variation calculator to find the constant of variation based on the 'x' and 'y' value.

Enter a number and a base into the calculator. The calculator will display the inverse log of the number and base entered. The base of the natural log is equal to e=2.71828. The standard base for log is base 10.

Direct, Inverse and Joint Variation. Solve the variation problems below. Note: Each problem has two (2) answers. Decimal answers should be rounded to the nearest hundredth. If y = kx, x and y vary directly. If y = k/x, x and y vary inversely. If z = kxy, z varies jointly with x and y.

inverse variation. With an inverse variation, y is inversely proportional to x. This relationship can be shown by the equation, xy 5 k, or y 5 , where k is the constant of variation. k x y x I can use this equation to decide how many packages I could buy if the price of one package is \$2.50, by substituting \$2.50 for the price per package (y) and

With direct proportionality we have c = x / y which we can also express that as c / 1 = x / y and solve for c using the calculator above. If y = 5 for x = 20, then we have c / 1 = 20 / 5 hence c = 4. With inverse proportionality c = x · y which we can also express that as c / x = y / 1 and again solve for c. If y = 2 for x = 10, then we have c ...
