The point $P\,$ lies on the curve with equation $y = 3xe^{x^2}$ with $x$ -coordinate 1.

Find an equation of the tangent to the curve at the point $P$ .

[5]

The tangent intersects the $x$ -axis at the point $A\,$ and the $y$ -axis at the point $B$ . Find the exact area of the triangle $A O B$ , where $O\,$ is the origin.
