Question

projection of vector P on vector Q.
​

Answer 1

Answer:

Projection of any vector p on q which is equivalent to projection of q on p, separated by an arbitrary angle 't' is the norm of the projection of p in the direction of q , or vice-versa. ... The dot product is defined as p . q which is the summation of product of individual components of the vectors p and q

Answer 2

Projection of P→ on Q→ is P cos θ, where θ is the angle between P→ and Q→ . Also, P cos θ=P→.Q^.
