### What is the difference between joint and combined variation?

Joint variation is direct variation to more than one variable (for example, d = (r) (t)). With combined variation, we have both direct variation and indirect variation. joint variation combined variation. Sometimes there are equations or circumstances where you actually have things that vary in more than one element so example of that is in ...

### What is the formula for joint variation?

Solution: First set up the equation. a varies jointly with b and c. ... Find the value of the constant, k. Given that a = 12 when b = 1 and c = 6 Rewrite the equation using the value of the constant 'k' Using the new equation, find the missing value. So, when a varies jointly with b and c and If b = 2 and c = 3, then the value of a is 12.
