what they mean by tangent planes sir in question..pls once tell its formulae
had it said normal then we would use directional derivative formulae
but i am not getting of tangent formulae
sir please once reply
wait ..
Normal to surface OR normal to tangent both are same at a POINT. So here I have find normal to surface which is easy .
And this is the formula for finding angle between two planes or between two tangent planes at a POINT , where n denotes normal vector to surface.
feel free to ask again...
ok sir got it .....thank u sir
