# Self checking trig equations

Hello!

I thought I had this activity working, it’s close, but not 100 percent. I don’t understand why only some of the equations are counted as correct using the CL that I have there. It works for certain values, but not all, even though the equations are equivalent.

Any suggestions?

It looks like you are able to type fractions or decimals in each input box except for the b value on screen 4. Rather than checking for latex form \frac{1}{2}, I set it to 0.5 and then was able to enter either .5, 0.5, or as a fraction, ½.
correctC = table.cellNumericValue(3,2) = \frac{1}{2}
