Make x the subject of the equation: y = 4(x+2)/5x-1

1st multiply out the brackets: y = 4x + 8 / 5x - 1 Next multiply both sides by the denominator onf the RHS: y(5x-1) = 4x + 8 Again, multiply out the brackets: 5xy - y = 4x + 8 Rearrange the equation so that ...

solve the differential equation dy/dx = 6xy^2 given that y = 1 when x = 2

First step is to seperate the variables (EQ1) : (1/y^2) dy = 6x Then we integrate each side seperately giving us (EQ2) : -1/y = 3x^2 + C (remembering to add 1 to the power and divide by the new power) subbin...

How would you determine what sort of stationary point this curve has? x^3 - 6x^2 + 9x - 4

I would differentiate it and then turn it into an equation to find the points where the gradient equals zero. With these points at hand, I would take a second derivative, this tells me how the gradient chang...
