When two vectors are perpendicular, their a) Dot product is zero b) Cross product is zero c) Both are zero d) Both are not necessarily zero 2. The cross product of the vectors 3i + 4j – ...We can either use a calculator to evaluate this directly or we can use the formula cos-1 (-x) = 180° - cos-1 x and then use the calculator (whenever the dot product is negative using the formula cos-1 (-x) = 180° - cos-1 x is very helpful as we know that the angle between two vectors always lies between 0° and 180°). Then we get:

Now given, a system of vectors is said to be coplanar if they are linearly dependent. If the vectors lie on the same plane then we can easily find ${\text{a,b,c}}$ and if two vectors are not parallel then the third vector can be expressed in the terms of the other two vectors. Therefore, they are linearly dependent. So II statement is also correct.(Considering the defining formula of the cross product which you can see in Mhenni's answer, one can observe that in this case the angle between the two vectors is 0° or 180° which yields the same result - the two vectors are in the "same direction".)

Since the dot product is 0, we know the two vectors are orthogonal. We now write →w as the sum of two vectors, one parallel and one orthogonal to →x: →w = …If and only if two vectors A and B are scalar multiples of one another, they are parallel.
