1. The problem statement, all variables and given/known data z = 2x^2 + 5y^2 +2 C is cut by the plane x = 2 Find parametric eqns of the line tangent to C @ P(2, 1, 15) 2. Relevant equations z = 5y^2 + 10 dz/dx = 10y dz/dx (1) = 10 3. The attempt at a solution z = 10y + 15 y = t + 1 if the slope is 10/1 then delta z = 10 and delta y = 1. Therefore those values are multiples in front of t for the z and y parametric eqns respectively. Is this correct? Thanks in advance.
