1. How can i determine the angle between two vectors
2. The Component of vector ( a vector, given below ) along the direction of i+j
3. Let there be a vector and b vector , then find component the component of a vector along perpendicular direction of b vector.
Please also do tell me what do you mean by along the direction and perpendicular to some vector and projection.
a vector=2i + 3j + 4k
b vector = 3i + 4j + 5k
