  1. Hey I know how to do the entire question my whole method was correct but instead of taking gradient of tangent 2/3 I did careless mistake and put 1/3

    REST of my method was 100% correct with explaination.
    Would I even get few marks or a straight zero :(

    I hate myself for this careless mistake :(

  2. Most probably you will get around 4-5 points out of 7.

    REST I DID ALRIGHT

  5. That's bad Uzair :(
    You'll get some points (did you write anything about the product between the gradient of the tangent and the gradient of the normal?)

  6. Yes I feel real bad because I knew the whole logic but still did careless mistake.
    Yes I wrote m1 x m1 =-1
