Explanation Given: Curve = r ( t ) = 〈 4 , sin 2 t , cos 2 t 〉 Formula used: Tangent vector = T(t) = r ' ( t ) | | r ' ( t ) | | Normal vector = N(t) = T ' ( t ) | | T ' ( t ) | | Calculation: First we need to find tangent vector before finding normal vector. Tangent vector = T(t) = r ' ( t ) | | r ' ( t ) | | Now, r ' ( t ) = 〈 0 , 2 cos 2 t , − 2 sin 2 t 〉 ⇒ | | r ' ( t ) | | = ( 2 cos 2 t ) 2 + ( − 2 sin 2 t ) 2 = 4 cos 2 2 t + 4 sin 2 2 t = 4 ( cos 2 2 t + sin 2 2 t ) = 4 ( 1 ) = 2 ∴ T(t) = r ' ( t ) | | r ' ( t ) | | = 〈 0 , 2 cos

Vector Arithmetic

Vectors are those objects which have a magnitude along with the direction. In vector arithmetic, we will see how arithmetic operators like addition and multiplication are used on any two vectors. Arithmetic in basic means dealing with numbers. Here, magn…
