when we say it is linearly independent
and also my friend argue with me that orthonormality implies linear independence but i was not satisfied please help :smile:
i think i didn't get the calculas of variation or the euler's method(form).if u vl refer me some books which deals with abc...to xyz...please recommend and also please told me that wht actually we are doing while dealing with this method whts our main purpose is?
Thanx i understood that this partial derivative = zero so entire term inside the bracket is equal to some constant ad by the elimination process of constants we get a stright line in 3-dimension right or,,,,,,,,,,,,,,,,,:smile:
i couldn,t found the method to write the proper derivative in square root (in Newton method , dot put on variable) but i tell u that i have taken their dervative with respect to time and using the limits from t1 to t2 and used the variational principle of minima but further solved it but ....as...
i m little confusd in (finding the shortest distance b/w two points is a straight line in three dimensions)i have solved it but nothing found any accurate result
[ds][/2]=[dx][/2]+[dy][/2]+[dz][/2] is the distance in 3-dimension b/w 2 points then
how we can start and how we can take...
