Expert Solution
Step 1

The parametric form of the tangent line is 

x=x0+aty=y0+btz=z0+ct

where, (a,b,c) is the direction vector and x0,y0,z0 is the point of tangent line. 

Let us consider the curve f(x,y,z)=cg(x,y,z)=d

To determine the tangent line at P is obtained as

  1. Take two variables in the form of one variable and determine the implicit derivative at P
  2. The implicit derivatives will be the direction vector of the tangent line '
