I am struggling witth this problem because I don't know how to do this problem can you help me and can you do this step by step without skipping any steps because I need to follow along so I CAN UNDERSTAND IT And can you label it as well

**Vector Functions and Curvature** Let \( \mathbf{r}(t) = \langle t^2, 4t - 3 \rangle \). **Problem:** (a) Find \( \mathbf{T}(t) \) and \( \mathbf{N}(t) \). (b) Find the decomposition of \( \mathbf{a}(t) \) into its tangential and normal components. **Solution:** To solve part (a), first find the unit tangent vector \( \mathbf{T}(t) \) and the unit normal vector \( \mathbf{N}(t) \). For part (b), decompose the acceleration vector \( \mathbf{a}(t) \) into its tangential and normal components by calculating the tangential and normal accelerations. This problem involves steps such as differentiating \( \mathbf{r}(t) \) to find the velocity and acceleration vectors, normalizing the velocity vector to obtain \( \mathbf{T}(t) \), and then differentiating \( \mathbf{T}(t) \) to find \( \mathbf{N}(t) \). The tangential and normal components of the acceleration will be derived from these vectors.
