Events prior to trigasm include various mathematical calculations and trial and error methods in an attempt to produce an answer that seems reasonable. Upon successful verification of correctness, the problem solver reaches trigasm as excitement, relief and accomplishment are experienced. Audible responses due to trigasm may or may not be present.
The trigonometry class was silent as the students were taking their last test of the semester. 5 minutes were left on the clock and everyone was anxiously finishing up the last of their problems. A cute girl in the corner yelled, "Yes!!!!" in intense excitement as she had just verified the last of her answers to be correct. Clearly, she had just experienced a trigasm.
Jake: Dude, that test was so hard, wasn't it?!
Bob: Yeah, at first it was pretty difficult. Toward the end I experienced a couple of trigasms though so I think I did alright overall.
