# Understanding and Applying Trigonometric Operations as an ARE Candidate

Hey Everyone,

As noted in the recent ARE Update, the calculator provided within the ARE testing application has been updated to better serve candidates. The new features include a history function as well as a more visible and easier to use memory function.

**This new calculator provides all necessary standard calculator functions and no longer includes scientific buttons (sin, cos, tan, etc.).** Does this mean as a candidate you are NOT going to need to calculate the angle of a condition using trigonometry? That is correct, you are NOT going to need to calculate the angle of a condition using trigonometry on the ARE. If you are presented with an angular condition, the necessary angles will be provided within the question.

Does this mean as a candidate you do NOT need to calculate the cosine of an angle as part of a formula, such as calculating lighting levels? That is correct, you are NOT going to need to calculate the cosine of an angle as part of a formula related to calculating lighting levels. For questions such as this, the appropriate value of cos Θ will be provided.

**ARE candidates will need to continue to understand trigonometry and be able to appropriately apply given information to architecture related questions. **

NCARB continues to author new items for the ARE and replace legacy items. As this has been occurring, we are removing the need for candidates to complete mundane calculations or look up necessary formulas from the reference tab. Newly authored items are written in a way that provides candidates any needed formulas and relevant preliminary values. Candidates will need to continue to be able to demonstrate the ability to appropriately apply the information given while completing standard calculations using the tools provided.
