WebThe given vector is a = i + 2 j + 2 k. Its magnitude is, a = √ (1 2 + 2 2 + 2 2) = √9 = 3. The unit vector parallel to a is: ^a a ^ = a / a = ( i + 2 j + 2 k) / 3 = (1/3) i + (2/3) j + (2/3) k Answer: The required unit vector is (1/3) i + (2/3) j + (2/3) k. WebNov 16, 2024 · With normal functions, y y is the generic letter that we used to represent functions and →r (t) r → ( t) tends to be used in the same way with vector functions. Next, we need to talk about the unit normal and the binormal vectors. The unit normal vector is defined to be, →N (t) = →T ′(t) ∥∥ →T ′(t)∥∥ N → ( t) = T → ′ ( t) ‖ T → ′ ( t) ‖
