# Radian and Degree with Graphing Calculator

Hello everyone,

I use a TI-83 Plus and I'd like to know if there is a quick way to convert an angle from radian to degree and vice versa. I am not referring to multiplying by (pi/180) or (180/pi).

Thanks!

hit mode, it's at the top next to the 2nd button, and switch from radian to degree.

I actually wanted to ask whether the graphing calculator can convert a number to either radians or degrees. For example, if I typed in 145, would it be possible to press a few buttons to get the equivalent radian measure?

You have already mentioned one way of doing it, and matticus posted another. Here's another way: Divide by 57.3 (approx.). [This is essentially the same as multiplying by pi/180]

type in your angle in degrees and then go to angle -> the degree symbol and I think it outputs the answer in radians

If your mode is set to degrees
