AI Thread Summary
Bi-quadratic equations can be represented in 3-dimensional graphs, with Z defined as a function of X and Y. The equation Z = a + bX + cX² + dY + eY² + fXY describes a surface in three-dimensional space. To visualize this in two dimensions, one can create contour plots in the XY plane or take slices by setting either X or Y to a constant value. This approach allows for overlapping graphs or simplified representations. Utilizing these methods can effectively illustrate the relationships within the bi-quadratic equation.

Trying to solve a bi-quadratic eq. so I can graph in in x and y , but Z means this is a 3-D graph? , is it possible to have a overlapping graph or any ideas?? X= +100 &-100

Z= a + bX + cX² + dY + eY² + fXY

The equation Z= represents a surface in 3 space, as a function of X and Y. What are you trying to solve?
 
Im trying to break the equation into two parts to graph on a two dimensional axis or overlap the two on one graph, any ideas on dividing the equation into two??

It depends what you what to show. You could make a contour plot in the xy plane. Or take a slice along some other plane. Just set x or y to a constant and it becomes a 2D graph.
 
too easy, thank you

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
