**How do you find the inverse of a function on a scientific calculator?**

Use the Inverse Trigonometry Function or Inverse of a Reciprocal Function on Your Calculator. On scientific calculators, the –1 or x–1 button means to find the reciprocal of a number. This reciprocal button allows you to find the value of a reciprocal function when you’re working with a number.

**How do you find the inverse of a number on a calculator?**

To find the inverse of a function, write the function y as a function of x i.e. y = f(x) and then solve for x as a function of y.

### How do you tell if a matrix has an inverse?

If the determinant of the matrix A (detA) is not zero, then this matrix has an inverse matrix. This property of a matrix can be found in any textbook on higher algebra or in a textbook on the theory of matrices.

**Is there matrix division?**

For matrices, there is no such thing as division. You can add, subtract, and multiply matrices, but you cannot divide them. Since multiplying by1/3 is the same as dividing by 3, you could also multiply both sides by 1/3 to get the same answer: x = 2.

**How do we find the inverse of a function?**

Finding the Inverse of a Function

- First, replace f(x) with y .
- Replace every x with a y and replace every y with an x .
- Solve the equation from Step 2 for y .
- Replace y with f−1(x) f − 1 ( x ) .
- Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
