Answer:
I think the answer to the equation is 4.
The components of parallel and perpendicular to are and , respectively.
Step-by-step explanation:
Let be and , the component of parallel to is calculated by the following expression:
Where is the unit vector of , dimensionless and is the operator of scalar product.
The unit vector of is:
Where is the norm of , whose value is determined by Pythagorean Theorem.
The component of parallel to is:
Now, the component of perpendicular to is found by vector subtraction:
If and , then:
