Find Tangent Line Approximation. The tangent plane will then be the plane that contains the two lines L1 L 1 and L2 L 2. We are now ready to use the tangent line approximation formula.
Using this we find our approximation for V1253 is. If we know the tangent line approximation Lx fa fax a then because La fa and La fa we also know both the value and the derivative of the function y fx at the point where x a. The tangent line to approximate 10104 as follows.
Find a formula for the tangent line approximation Lx to f at the point 2 1.
In this case f 1 and f 1 are easy. Find a formula for the tangent line approximation Lx to f at the point 2 1. The tangent plane will then be the plane that contains the two lines L1 L 1 and L2 L 2. Show your work carefully and clearly.
