This equation has no real roots, as when we test the equation with the formula b² - 4ac, we get 2² -415 = 4 - 20 = -16. As this is negative we can be assured that this equat...

y = 4x³ - 7x -10The gradient of the function at any point can be found using its derivative:dy/dx = 12x² - 7The gradient of the function, m₁, at (2,8) is equal to the grad...

f(x) = 4x² - 16ln(x-1) -10, f'(x) = 8x - 16/(x-1), so if f'(x)=0, then 8x - 16/(x -1)=0, 8x(x-1) - 16 = 0, 8x²- 8x - 16 =0, 8(x²- x - 2) = 0, x² - x - 2 = 0, (x...

To integrate this simple equation add one to the power then divide by the new power for example. 2x^2 becomes 2/3x^3 4x becomes 2x^2 and 1 becomes x plus constant c so the overall integrated equation is 2...

First notice that this is an equation that will require implicit differentiation since C cannot be explicitly written in terms of either x or y. Thus we must differentiate each term with respect to x:-the...
