r = t i + 6 /t j . differentiating WRT t , dr /dt = i - 6 /t2 j at t =2
: dr /dt = i - 6 /4 j = i - 3 /2 j
Inter changr the x , y components and attach - ve sign to one of the component
normal vector is : 3/2 i + j its magnitude is[ ( 3/2)2+ 1]1/2= (13)1/2/2
unit normal vector is [ 3/2 i + j ] / (13)1/2/2= 2 [ 3/2 i +j] /(13)1/2 + (3i+2j)/ ( 13) 1/2
