Something’s not working the way it seems like it should.

When I …calculate the trig value of cos pi/3

I saw …the graphing component gave the value as 0.50000000000001

But I expected …the value to be 0.5

(It works correctly on the graphing calculator but not the graphing component, this is causing the exact values not to be recognized as the same answer)

Here’s the link to the page, dashboard, or activity:
