A function is defined for http://ta2.maths.ed.ac.uk:8080/maple...bmolepegik.gif by http://ta2.maths.ed.ac.uk:8080/maple...oofflnlemc.gif.

Given that the function is even, what is the value of http://ta2.maths.ed.ac.uk:8080/maple...gedjcfchba.gif?

Could someone explain how to solve this problem cheers.
