A cubic equation is an algebraic expression that involves the variable of the highest degree as a cube. It has the general form ax^3 + bx^2 + cx + d = 0, where a, b, c, and d are constants and x ...

A cubic graph is any graph which has an \(\text{x}^3\) in its equation. Cubic graphs are still curved but can have more than one change of direction in them.

Everything in physics is described by an equation. Equations can describe the shape of lines, curves, surfaces, and just about any object you can think of. In fact, you’d be hard-pressed to think of ...

As the tangent is a straight line, the equation of the tangent will be of the form \(y = mx + c\). We can use perpendicular gradients to find the value of \(m\), then use the coordinates of P to find ...
