Question
If \( f(x, y) = x^2 + 4y^2 \), use the gradient vector \( \nabla f(3, 1) \) to find the tangent line to the level curve \( f(x, y) = 13 \) at the point \( (3, 1) \). 1. \( 2x + 8y = 13 \)
Transcribed Image Text:If \( f(x, y) = x^2 + 4y^2 \), use the gradient vector \( \nabla f(3, 1) \) to find the tangent line to the level curve \( f(x, y) = 13 \) at the point \( (3, 1) \). 1. \( 2x + 8y = 13 \)
### Linear Equations This section provides a series of linear equations for practice and study: 1. \(3x + 4y = 13\) 2. \(6x - 8y = 13\) 3. \(6x + 8y = 13\) 4. \(3x - 4y = 13\) These equations represent straight lines in a two-dimensional plane. Each equation can be solved for \(x\) or \(y\) to find specific points on the lines or to understand their slope and intercept properties better.
