Domain Definition Math For Dummies

In reference to the coordinate plane tangent is y x and cotangent is x y the domains of both functions are restricted because sometimes their ratios could have zeros in the denominator but their ranges are infinite.

Domain definition math for dummies. Domain rarr function rarr. It also can t be 1 because that would give us a denominator of 0. The domain of a function consists of all the values that you can use as input into the function rule.

Domain of a trig function. The domain is another of that function s characteristics because different functions have different numbers that you can input and have the outputs make any sense. Let s find the domain of the function.

We can t have a negative number in the square root so x can t be a number less than 1. If x 1 then the range is all real numbers less than 1. Illustrated definition of domain of a function.

The tangent and cotangent are related not only by the fact that they re reciprocals but also by the behavior of their ranges. All the values that go into a function. In this case x is defined for all real numbers greater than 5.

Then the range is. The output values are called the range. So the range is.
