MHB Linear Approximation: Intro to Physics Problem

Click For Summary
Linear approximation is frequently utilized in physics to simplify complex problems by estimating values near a given point. The discussion highlights the importance of understanding this concept as a foundational tool in physics. Participants express a sense of uncertainty about their initial attempts but receive reassurance that their approach appears correct. The conversation suggests a willingness to explore further examples to solidify understanding. Overall, linear approximation serves as a critical method for solving introductory physics problems effectively.

never done this before so this is an intro problem
it mentioned that LA is used in Physics a lot
hopefully correct no ans in bk(Speechless)

Thread 'Problem with calculating projections of curl using rotation of contour'

Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
