Problem on Wolfram online server

Today I found a problem on Wolfram online server.
Though this is my 1st post, its requested to remove that problem as soon as possible
link-Wolfram|Alpha: Computational Intelligence

BUG REPORT- C and D have to be interchanged, else many will get confuse and get wrong results.

Wolfram helped me in many questions, now it’s my time to help the community.
