Functions of 2 Or More Variables

Find an equation of variation where a varies jointly as b and c, and a = 30 when b = 2 and c =3. Solution Write the joint variation equation that resembles the general joint variation formula y = kxz. Let a = y, x = b, z = c. y = kxz a = kbc 30 = k (2) (3) k = 5 Final Answer Therefore, a = 4bc is the required equation of joint variation.

Joint Variation Equations Calculator Joint Variation Equations Calculator Enter Joint Variation Parameters: z varies jointly with y and x, and z = 192 when x = 2 and y = - 6, solve for z when b = 2,c = 3 The statement denotes a relationship of z = kyx where k is a constant

It is said that one variable varies directly as the other. The formula for direct variation is y=k ...

Joint variation describes a situation where one variable depends on two (or more) other variables, and varies directly as each of them when the others are held constant. We say z varies jointly as x and y if z = k x y for some constant k. Example: If z is jointly proportional to x and y and z = 6, when x = 3 and y = 4, find z when x = 7 and y = 4.
