Determine the magnitude of a vector
WebApr 22, 2016 · Given $$\vec x= \vec a+t\vec b$$ where $$ \vec a , \vec b $$ are non zero vector for all real number t . The question asked about the minimum magnitude of x and the answer shown is $$ \frac {-\vec a \cdot \vec b}{\vec b\cdot \vec b}$$ How do i arrived at such conclusion? I tried to take square but it didn't work out. WebTo find the magnitude of a vector from its components, we take the square root of the sum of the components' squares (this is a direct result of the Pythagorean theorem): (a,b) =\sqrt {a^2+b^2} ∣∣(a,b)∣∣ = a2 + b2 For example, the magnitude of (3,4) (3,4) is \sqrt {3^2+4^2}=\sqrt {25}=5 32 +42 = 25 = 5. Problem 1.1 \vec u = (1,7) u = (1,7)
