Required argument used by the TAN formula.

Examples for the tan formula

Copy these examples into a spreadsheet and adjust the ranges for your own data.

TAN syntax pattern

=TAN(radians)

Use this TAN pattern as the starting point for your spreadsheet formula.

TAN in a worksheet

=TAN(radians)

Returns the tangent of an angle in radians.

When to use TAN

Use TAN when you need to return the tangent of an angle in radians.

  • Convert and calculate angles.
  • Model geometry, waves, and other trigonometric relationships.

How TAN works in Quadratic

In Quadratic, TAN follows the syntax TAN(radians). The function works inside Quadratic formulas and can be combined with spreadsheet ranges, tables, and other formulas.

Common TAN mistakes

Most TAN issues come from mismatched argument types, ranges that do not cover the intended data, or optional parameters being omitted when the default behavior is not what you expected.

  • Check each required parameter before copying the formula across a sheet.
  • Confirm that ranges line up with the rows or columns you intend to analyze.
  • Use Quadratic AI to explain or debug the formula when the result looks wrong.

Struggling with formulas? Use Quadratic AI.

Spreadsheet formulas are powerful, but they get painful fast. A TAN formula can start simple, then turn into logic that is hard to understand, easy to break, and difficult to share with the rest of your team.

Quadratic AI helps you write formulas, explain formula logic, debug broken references, and move beyond formulas when advanced analysis needs Python, SQL, charts, or connected data.

Why formulas slow teams down

  • Long formulas become hard to read, understand, and trust.
  • Formula logic breaks when rows, columns, or assumptions change.
  • Manual updates make dashboards and reports fragile over time.
  • Complex formulas are difficult to explain, review, and share with teammates.
  • Advanced analysis quickly outgrows formula-only workflows.
