Trigonometry SparkCharts (SparkCharts, 70) Reissue Edition

I am a senior returning to school and while the mind is pretty sharp still some things from my original school days have disappeared. The spark charts are a handy way to be prepared with the names, constants equations etc that are required. They are also well printed on tough material and punched to fit in a notebook. I am returning to school for my doctorate and I have bought 5 of these

This is a great reference item if you need formulas

Got this for a class and it has a lot of useful info

I got this for my pre-calculus class and I'm still using it in my third year of calculus. It comes in handy and it's got tons of relevant information!

Great reference sheet to use for precal college class!

Very helpful

My son uses this as a reference in his trig class; the amount of information on this card makes it a worthwild reference while doing homework.
