# IMTAN

Formulas / IMTAN
Calculate the tangent of a complex number.
`IMTAN(inumber)`
• inumber - required, complex number

## Examples

• `=IMTAN("4+3i")`

The function can be used to return the tangent of a complex number. This example returns the tangent of the complex number 4+3i, which is -0.009989949748.

• `=IMTAN(1.5)`

The function can also be used to calculate the tangent of an angle expressed in radians. For instance, this formula returns the tangent of 1.5 radians, which is equal to 2.18503986326.

• `=IMTAN(30)`

The function can be used to calculate the tangent of an angle expressed in degrees. For example, this formula returns the tangent of 30 degrees, which is equal to 0.57735026919.

• `=IMTAN(100)`

The function can be used to calculate the tangent of an angle expressed in grads. For instance, this formula returns the tangent of 100 grads, which is equal to 1.73205080757.

## Summary

The IMTAN function calculates the tangent of a complex number, which should be provided in x+yi or x+yj text format.

• The IMTAN function calculates the tangent of a complex number which should be formatted as x+yi or x+yj.
