• Example 1:If we take an equation y = f(x) = In x, i.e. y depends on x. if we take different differentvalues of x
then we find some different values of y.
x = 1 then y = In 1 = 0, x = 2 then y = 0.693
x = 3 then y = 1.09, x = 5 then y = 1.60x = 7 then y = 1.945
Important:
• In Mathematics, independent variables are those values that determine the value of other variables. Dependent variables are those, whose values are determined with the help of the independent variable.
EXERCISES:
• If I drink mountain dew before bed,then I will not sleep very much.
• (Independent or Dependent)
1. DrinK mountain dew.____________
2. amount of sleep. _______________
Hypothesis example:
• If water temperature increases, then the amount of sugar dissolved in the water will also increase.
• Independent or dependent?
• 1. amount of sugar that dissolves, measured in grams. _______________________
• 2.water temperature_________________
