How can we derive the 'suvat' equations of motion v=u+at and s=(u+v)t/2

v=u+at Using a velocity time graph with constant acceleration, (graph provided as visual aid in tutorial) with initial velocity u and final velocity v, we can see that the graph is a straight line. ...

Compute the integral of f(x)=x^3/x^4+1

A basic function of integration states that: for a function f(x), the integral of f'(x)/f(x) = ln[f(x)] (the natural log of the modulus of f(x)). Take the denominator of f(x), x⁴+1. We will ref...

A curve has parametric equations x = 1 - cos(t), y = sin(t)sin(2t) for 0 <= t <= pi. Find the coordinates where the curve meets the x-axis.

If the curve is meeting the x-axis, notice that this means y = 0. So we must solve sin(t)sin(2t) = 0 for t within the given bounds. Using a trigonometric identity sin(2t) = 2cos(t)sin(t), we obtain sin
