Homework Statement
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)
Homework Equations
z = 5y^2 + 10
dz/dx = 10y
dz/dx (1) = 10
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.
