Hi. I am stuck on a question so please help me.1. Two vectors are given a = (3.0i + 5.0j ) and b = 2.0i +4.0j. Find a) a x b, b) a b, c). (a + b) c?Could you answer another question ? Thank you.2). show that a ( b x a)is zero for all vectors a andb ( Just the definition of the direction of the cross productinstead of elaborate mathematical proof) b) what is the magnitudeofa x (b x a) if there is no angle θ between the direction ofa and b( please note that all a and b are vectors)
Are there any questions left?
