How bad is that?
I'm doing some trig to do with lenses and NAs and stuff and I've forgotten the basic trig stuff :-)
What's worse is that I couldn't remember how to spell sohcahtoa either... (never needed it at school cause I hadn't lost my mind) I - got socatoa... which wasn't enough letters!). Then I remember that "some officers have..." and could build it back up from there :-)
On the other hand I guess I knew tan didn't involve they hypotenuse - so it was obvious that the other two needed an H somewhere... :-)
Where is my mind?
