Difference between directly proportional and inversely proportional
Answers
Answer:
The term directy proportional is used when the change in values of two related variables have same sign.inversly proportional is used when the change in the values of two related variables have opposite sign..for example if we write Y is directly proportional to x,then we denote Y=x...for inversely proportional we write it as Y=1/ X...that is if one increase other decreases ...so it's sign changes for inversely proportional....but for directly proportional one value changes according to other value equally and their sign seems to be equal...
Answer:
Like Direct and Indirect(Inverse) Unitary Methord, Direct and Indirect(Inverse) Proportion stands for same. Direct Proportion means when both mean and extreme increases or decreases at the same time. In Indirect(Inverse) Proportion, when mean or extreme increases or decreases the other becomes opposite(if mean or extreme increases other decreases or if mean or extreme decreases the other increases).
