I haven't taken this in school yet but I love math and physics and join lots of competitions. I have a problem with sine, cosine, and tangent, that I...
I am trying to understand what is meant by a bilinear form. It seems to be some constraint on a map of two vectors to a field. I would be grateful if some...
I have interesting trigonometric expression for professionals in mathematical science. So, here it is: $$\sin\dfrac{3\pi}{14}-\sin\dfrac{\pi}{14}-\sin\dfr...

Given that $\tan 2x+\tan x=0$, show that $\tan x=0$ Using the Trigonometric Addition Formulae, \begin{align} \tan 2x & = \frac{2\tan x}{1-\tan ^2 x} \...
I just have a question about directional derivatives. I know that for a unit vector $v$, it is $\nabla f \cdot v$ (where $v$ is the direction we want to f...
