Find a unit vector in the same direction as the given vector. a = 21i + 20j
Added by Joseph J.
Step 1
The magnitude of a vector is given by the formula: ||a|| = sqrt(a1^2 + a2^2 + ... + an^2), where a1, a2, ..., an are the components of the vector. In this case, we have: ||a|| = sqrt(21^2 + 20^2) = sqrt(841 + 400) = sqrt(1241) Show more…
