Find the Unit Tangent and Unit Normal Vectors $\mathbf { T } ( t )$

Short Answer

Find the unit tangent and unit normal vectors $\mathbf { T } ( t )$ and $\mathbf { N } ( t )$ for the curve C defined by $\mathbf { r } ( t ) = t \mathbf { i } + 2 t ^ { 2 } \mathbf { j }$ Sketch the graph of C, and show $\mathbf { T } ( t )$ and $\mathbf { N } ( t )$ for $t = 1$
