An introduction into Variation

​When you start studying algebra, you will also study how two (or more) variables can relate to each other specifically. The cases you’ll study are:

Direct Variation , where both variables either increase or decrease together

Inverse or Indirect Variation, where when one of the variables increases, the other one decreases

Joint Variation , where more than two variables are related directly

Combined Variation, which involves a combination of direct or joint variation, and indirect variation

These sound like a lot of fancy math words, but it’s really not too bad. Here are some examples of direct and inverse variation:

Direct : The number of dollars I make varies directly (or you can say varies proportionally) with how much I work.

Direct : The length of the side a square varies directly with the perimeter of the square.

Inverse : The number of people I invite to my bowling party varies inversely with the number of games they might get to play (or you can say is proportional to the inverse of ).

Inverse : The temperature in my house varies indirectly (same as inversely) with the amount of time the air conditioning is running.

Inverse : My GPA may vary directly inversely with the number of hours I watch TV.

P.S You got the drill? This is not to expressly treat variation but to introduce it to you.

  1. Well Applied, I believe if math or further maths as we studied in school then is literally and logically understood and explained by our teachers ,the motivation to learn faster will undoubtedly by much,nevertheless its source of inspiration to those in the field now..
