To find the inverse of a 2x2 matrix.
\n" ); document.write( "\"A=%28matrix%282%2C2%2Ca%2Cb%2Cc%2Cd%29%29\"
\n" ); document.write( "Then,
\n" ); document.write( "\"A%5E%28-1%29=%281%2F%28ad-bc%29%29%2A%28matrix%282%2C2%2Cd%2C-b%2C-c%2Ca%29%29\"
\n" ); document.write( "So,
\n" ); document.write( "\"1%2F%28ad-bc%29=1%2F%287%283%29-%28-4%29%28-5%29%29=1%2F%2821-20%29=1\"
\n" ); document.write( "\"A%5E%28-1%29=%28matrix%282%2C2%2C3%2C4%2C5%2C7%29%29\"
