1. JOINT VARIATIONS

2. If there are more than two quantities in a variation then the variation is called a joint variation, and the quantities vary jointly Definition

3. If z varies directly as x and y and k is constant. Then we can say, Example:

4. For different values of x, y, and z

5. Therefore

6. And

7. If z varies directly as x and inversely as y and k is constant. Then we can say, Example:

8. If z varies inversely as x and inversely as y and k is constant. Then we can say, Example:

9. The end
