Take a picture and get your answer, now the latest update is like this and with this extra feature-Now you can convert radians to degrees and find the value of sum given in sigma notation Î£. And all the good features are not locked behind a paywall. This is much more convenient then having to use the x to get the y or vice versa.

Very good nice,, helped me understand some math stuff bc it explains the steps to solving the equation / expression. I have no words to express it. This app has been a great help for me over the years, and even more helpful now in highschool, i think that one feature should be add on the free version.
