An Equation is an Algebraic sum of many types of functions.
Here the variable (or) output (or) value of ‘y’ depends on ‘x’ and angle .
So that, ‘y’ is dependent variable and ‘x’ is independent variable.
2)The overall working (equation) of our human body is the group of many functions , those are Eye, Ear, Nose, Mouth, Heart, Liver, Kidney ……
3)Working of computer having many functions.
4)Working of Satellite.
