Trigonometry and calculus.

If you’re doing Trigonometry or even calculus get this calculator, when it comes to inverse functions, it helps you so much because it gives you the number with a square root. If you did this on a T I 84 it would just give you decimal numbers instead of let’s say 1 over square root 3.
