How to show special characters in Android?
===

I am developing a native app which consists of some mathematical formulas which will be shown to user. Formulas will be like..   

             
  ![Formulas][1]

I want to display such formulas in my app, but i don't use these special characters in Android. I want to display each formula individually in a list view......  If i am copying formula & if i am setting text to textview means it is showing like 

    txtv.setText("\\cos^2\\theta + \\sin^2\\theta = 1\\! ");

and getting output in the same pattern. So, can anyone help me how to use these mathematical special characters in Android.....
