Undergrad 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...- rapids79

Undergrad 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?- rapids79

Undergrad 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...- rapids79
