我有一个应用程序可以帮助人们使用微积分，我想让它看起来像实际的数学代码，而不是看起来像 x^2+(x^1/2)-4 的方程。项目中的代码如下。我已经研究过这个主题，但没有看到明确的解决方案。谢谢！
public class Limits extends Activity implements
OnClickListener {
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_MAX_OFF_PATH = 250;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
private GestureDetector gestureDetector;
View.OnTouchListener gestureListener;
String facts[] = {
//limits
"Find the limit as x approaches 0 of x^3+4x^2+6x+7",
"Find the limit as x approaches infinity of x/x^2",
"Find the limit as x approaches 3 of (x+3)^2/(x+6)",
"Find the limit as x approaches infinity of x^3/x",
"Find the limit as x approaches 3 of (x^2-6x+9)/(x-3)",
"Find the limit as x approaches 7 of 49x^2/7x",
"Find the limit as x approaches infinity of (2x^2-5x+3)/(x^2-7x+7)",
"Find the limit as x approaches 2 of (x − 2/x^2 − 19x + 34)",
"Find the limit as x approaches 6 of ((|x-6|)/(x-6))",
};
