If the angle between the vectors veca and vecb " is " pi/3 and the area of the triangle with adjacemnt sides parallel to veca and vecb is 3 , then a.b is

the angle between vectors veca × vecb and vecb × veca is

If the angle between veca and vecb is (pi)/(3) , then angle between 2veca and -3vecb is :

Statement I: The angle between the vectors vecA=hati +hatj and vecB=hatj+hatk is (pi)/3 . Statement II: The angle between vector vecA and vecB is theta =cos ^(-1) ((vecA*vecB)/(AB)) .

If angle between veca and vecb is pi/3 , then angle between veca and -3vecb is

If veca=hati+2hatj+2hatk,|vecb| =5 and the angle between veca and vecb is (pi)/(6) , then the area of the triangle formed by these two vectors as two sides is

If veca=hati + 2 hatj + 2hatk, |vecb|=5 and angle between veca and vecb is (pi)/(60, then the area of the triangle formed by these two vectors as two side is :
