    Magnetic field and Skin Effect

    I have been trying to understand the field theory from the basics and have come across a few things I have not understood a few things clearly: 1. The magnetic field strength is maximum at the center of the conductor and decreases with an increase in the distance from the center. I understand...

    Why is a negative sign not needed when swapping rows in matrix row echelon form?

    Hi..I have a very basic query...while solving a determinant, when we exchange/swap 2 rows we need to add a negative sign to the determinant. However, when we are trying to reduce a matrix to a row echelon form, when we swap 2 rows..do we need to add a negatice sign here as well? Well..from what...

    How Does Rotating an Ellipse's Major Axis Affect Its Equation?

    Hi..Thanks for the reply..am just starting out in software...need to implement a code that does that for a project...so, anyway...if I have a point A...how would I check if it lies within the rotated ellipse...is there any mathematical method like the tangential method that does that?

    How Does Rotating an Ellipse's Major Axis Affect Its Equation?

    Hi..I have a basic question regarding the equation of an ellipse. Let's say I ahve an ellipse with major and minor axes 2a and 2b respectively. Now, to check whether a point lies inside this ellipse, its fairly simple...I can just use the standars ellipse equation for that. Now, if my major axis...
