If a and b are two vectors , then `(atimesb)^(2)` is equal to

If a and b are two unit vectors such that a + b is also a unit vector, then |a-b|^(2)=

If veca and vecb are two vectors and angle between them is theta , then a. |atimesb|^(2)+(a*b)^(2)=|a|^(2)|b|^(2) b. |atimesb|=(a*b), if theta=(pi)/(4) c. atimesb=(a*b)hat(n) , (where hat(n) is a normal unit vector), if theta=(pi)/(4) d. |atimesb|*(a+b)=0

For any vectors a,b,|axxb|^(2)+(a*b)^(2) is equal to

For any vectors a,b,|axxb|^(2)+(a*b)^(2) is equal to

For any vectors a,b,|axxb|^(2)+(a*b)^(2) is equal to

If a and b are two non-parallel vectors having equal magnitude, then the vector (a-b) times (a times b) is parallel to
