WebThe angles which the vector i^+j^+rt2k^ makes withe X,Y and Z axes respectively are Solution Let the unit vector along x axis be i (cap) i+j+√2k=A is the given vector A.i= A i cosX =>1=2cosX =>X=60⁰ (angle made with the X axis) Let the unit vector along y axis be j (cap) A.j= A j cosY =>Y=60⁰ (angle made with the Y axis) WebWhen two nonzero vectors are placed in standard position, whether in two dimensions or three dimensions, they form an angle between them (Figure 2.44). The dot product provides a way to find the measure of this angle. This property is a result of the fact that we can express the dot product in terms of the cosine of the angle formed by two vectors.
