Misprint?

I'm wondering if there're some misprints in the text: Applying the Boe-Bot Digital Encoder

P.9: (see attached file) the forth expression
attachment.php?attachmentid=45736
My calculation's not the same as the text.
attachment.php?attachmentid=45738

P.10:
attachment.php?attachmentid=45737
When Left Wheel moves first, why does the new angle in the L VECTOR become (theta + delta)?
Shouldn't it be (theta - delta) according to the angles defined on P.8 ?
attachment.php?attachmentid=45739


Thanks~

    koolitude,

    You're right: there's an error in the formula for y1R, for which you have provided the correct expression. Fortunately, this appears to be no more than a typo, in that using your expression in the solution of y1R below, yields the expression given in the text. (Phew!)

    I'll make the necessary change and submit the corrected manuscript to Parallax.

    Thanks much for catching this and bringing it to my attension!

    -Phil

    Phil,

    You're welcome... =) It's really kind of you to answer my questions...

    I wanna understand the theory behind rather than just using the program you wrote straight away... That's why I am trying to read the text again and again; and I found that...

    By the way, if you know the answer for the L VECTOR, could you please let me know as well

    Thank you very much! =)

    koolitude.
