#### Question

Find the shortest distance between the lines whose vector equations are vecr = (hati + 2hatj + 3hatk) + lambda(hati - 3hatj + 2hatk) and vecr = 4hati + 5hatj + 6hatk + mu(2hati + 3hatj + hatk)

#### Solution

The given lines are   vecr = (hati + 2hatj + 3hatk) + lambda(hati - 3hatj + 2hatk) and vecr = 4hati + 5hatj + 6hatk + mu(2hati + 3hatj + hatk)

It is known that the shortest distance between the lines, vecr = veca_1 + lambdavecb_1 and ,vecr = veca_2 + muvecb_2 is given by, Therefore, the shortest distance between the two given lines is 3/sqrt19 units

Is there an error in this question or solution?
