# MATH152/April 2015/Question B 3 (b)

From User talk:BRIANCHAN

Hi Brian,

I think the solution doesn't explain how you get the parametric form, especially the relation between x, b_1 \times b_2, and a with the plane P_2, Also, the reason why you find b_1 \times b_2.

So it would be great if you rewrite the solution. Also, please use for vector x.

Thanks, Hyunju
