Sin(30°) =1/2 0.5
cos(30°) = (√3)/2
Note that the sin of an angle is equal to the cos of the complementary angle:
sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)
Answer:
independent variables : are variables that are self independent
dependent variables: are variables that depend on the independent variables
Explanation:
eg. As the pressure of the room increases its temperature increases
independent variable : the pressure of the room as its not effected by anything else (mentioned in the equation )
dependent variable : Heat of the room as it depends on the increases or decrease in pressure
