An object is moving counter-clockwise along a circle with the centre at the origin. At \(t=0\) the object is at point \(A(0,5)\) and at \(t=2\pi\) it is back to point \(A\) for the first time.

In mathematics, the tangent line to a curve at a point is a straight line that touches the curve at this point only. The tangent line can provide valuable insights into the properties of the curve, ...

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

The Mathematical Gazette is the original journal of the Mathematical Association and it is now over a century old. Its readership is a mixture of school teachers, college and university lecturers, ...

Abstract: It is a known fact that in a frame of the parabola based calculation for overhead line design the equation of the conductor curve in a span can be defined if the span length, the coordinates ...

Abstract: In the frame of the parabola-based sag-tension calculation for overhead line design, the necessary data for the derivation of the equation of the conductor curve in a span are the maximum ...
