Awasome Given A=2I-J 2K And B=-I-J K Ideas. Web find the angles between the vectors: Hence, this is the answer.

If a=5i+4j+2k, b=4i5j+3k and c=2ij2k. Determine value \[a\dot b
If a=5i+4j+2k, b=4i5j+3k and c=2ij2k. Determine value \[a\dot b from campusflava.com

Web cosθ= ∣2i+j−k∣∣i+j+k∣(2i+j−k).(i+j+k) cosθ= ( 4+1+1)( 1+1+1)(2+1−1) cosθ= ( 6)( 3)2. Web find the angles between the vectors: For the given cost function.

(A) 195 (B) −25I+35J−55K, (B) (A+2B)×(2A−B).


Hence, this is the answer. Comment on the need for parentheses in the cross products. Web find the angles between the vectors:

| A → + B → | = 1 2 + 1 2 = 2.


∴ for two vectors → a and → b if → c is the vector. Find the value of a and b. If a=3i−j−2k and b=2i+3j+k, find:

Web Cosθ= ∣2I+J−K∣∣I+J+K∣(2I+J−K).(I+J+K) Cosθ= ( 4+1+1)( 1+1+1)(2+1−1) Cosθ= ( 6)( 3)2.


Web explanation for the correct option: For the given cost function. Web we know that cross product of any two vectors yields a vector which is perpendicular to both vectors.
