The solution for the third question's first section is wrong, the procedure is right, but the final answer is right. f(-x)=-f(x) is an odd function.Thx for ur time, and i like ur lecture.

Apparently you did not notice the note following the link to the posted soltions: the solutions provided there are only for the tests for B02, B03 and B04; the other section (apparently, your own) has similar (but not identical) problems. No error; only different questions.

(Thanks.)

Actually, i have checked that and double checked the solution one more time. But f(-x)=-x* abs(x)/(1+x^2)=-f(x); in this case, the function is odd not even. Thx for ur time and prompt response.

I see; I thought you were referring to 3(c); apparently you were talking about 3(a). You are right. I forgot to type the minus sign. Corrected. Thanks for noticing.
