Is any function a relation?
Yes. All functions are relations, but not all relations are functions. Functions have to have only one y-value per x-value.
Is anyone of the six trigonometric functions a one to one?
They are all one-to-one as they all pass the vertical line test.
What is the functions and what is relation in trigonometry?
The same as in any other math class. All functions are relations but all relations are not functions. A function must have only one 'answer' in the range for each value of the domain. Relations are just pairing of numbers with no such restriction on the range.
How are linear equations and functions alike?
They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
What jobs use functions?
