- Homework Statement
- The resultant of two orthogonal vectors makes an angle θ with their difference. if magnitude of one is 2 times that of the other, find the value of sec θ.
- Relevant Equations
- |a+b|=sqrt(a^2 +b^2 +2ab)
But the answer in my book is given that sec(theta) =3. Where am I going wrong?
