I am trying to show that the smallest period of $sin(\theta)cos^n(\theta)$ is $\pi$ if $n$ is odd and $2\pi$ if $n$ is even. For $n=0,1$ this is quite simple, but I cannot seem to find a way to show this for $n=2$. I can show that $2 \pi$ is a period, ...
Richard Burton, Rex Harrison and Elizabeth Taylor star in one of the greatest screen spectacles ever made – the story of the Queen of the Nile and her love affairs with Julius Caesar and Mark Antony. The film is distinguished by superb performances from Burton and Harrison (nominated for an...

It seems intuitive that there will be a minimum value the horizontal speed can take at the times when the mass is directly below the point of suspension. More generally, if the horizontal displacement is x then some formula like ##ax^2+b\dot x^2 > c##. But I cannot think of a basi...
Transformation of Graph of {eq}f(x) {/eq} to {eq}f(x \pm a) {/eq} and {eq}f(ax) {/eq} The concept of transforming the graph of any given function, say f(x), helps us find the graph of a more complex function. For an example, if ...
