+Reflection Essay:
+
+*Got to learn about octave and hence learn how to solve equations directly using predefined functions
+	like fzero and fsolve.
+*How to create output file and input values into variables from an input file using methods like
+	fopen,load, fwrite etc.
+*We learnt about %f,%d and other formats and how to set the precision of the answer.
+
+Member contribution:
+
+All the three contributed equally.
