Hint: In this question, we have been given a condition of two vectors and we need to find the\[sine\] of the angle between them. According to the standard formula, the angle $\theta $ between two vectors \[\overrightarrow u \] and \[\overrightarrow v \;\...
Find the angleθbetween the vector,a=6i−j−4kandb=2i+j−6k. Angle between two vectors: In Vector Calculus, ifa→andb→are two vectors andθis the angle between them, then Cosine of angle between vectors is equal to the dot product of two vectors divided by the magnitude of the...
