Hyperbolas - Standard Form This is probably a simple question but if $y = \frac{1}{x}$ is a hyperbola, then how does it comply with the standard form of a hyperbola? !Standard Form of Hyperbola
In general, for any angle of rotation $\theta$ from the $x-$axis, we may apply the following change of variable to put a hyperbola in standard form: $ $x = x\cos\theta - y'\sin\theta$$ $$y = x'\sin\theta +y'\cos\theta.$$ Notice our hyperbola $xy = 1$ is rotated by an angle of $\frac{\pi}{4}$ from the

Quick question about a hyperbola in $\log-\log$ space Let $u=\ln(x)$ and $v=\ln(y).$ Is it correct to conclude that $uv=1,$ in $\log-\log,$ space is a hyperbola, but in $x,y$ space it is not a hyperbola?
It is indeed correct to conclude that in log-log space $\ln(x)\ln(y)=1$ is the hyperbola $xy=1.$ Taking the natural logarithm of each point of the plot

Equation of hyperbola from asymptote? > A line $y = 2x+5$ intersects a hyperbola only at a point $(-2,1)$. The equation of one of its asymptotes is $3x+2y+1=0$. If hyperbola passes through the point $(-1,0)$ then what...
As line $y=2x+5$ intersects the hyperbola only at a single point (but it is not tangent), then this line must be parallel to an asymptote. On the other hand, if $2x−y+λ=0$ and $3x+2y+1=0$ are the equations of its asymptotes, then the equation of the hyperbola is $$ (2x−y+λ)(3x+2y+1)=k, $$

Equation representing the branch of hyperbola Is there an equation representing the one branch of hyperbola ($x^2-y^2=1$). This is the regular hyperbola: ![enter image description here]( This is the expected curve:...
In order to "exclude" possible negative $x$ we can do the trick of taking the square root, since this is not possible for negative numbers, then cancel the square root by using a square. Thus the equation will be identical as the one above, but only defined on the positive numbers for $x$. $$(\sqrt ...

Is the graph of $y=\frac{k}{x}$ a hyperbola? Is the graph of the following inverse relation a hyperbola?$$y=\frac kx$$ If yes, is it the only kind of hyperbola whose equation is an explicit function?
Yes, $$y=\frac kx$$ is a hyperbola. In fact, it is a type of _rectangular hyperbola_ which you can read more about here. This means that a function $y(x)$ that takes the form $$y-k=\frac {k}{x-h}$$ is also hyperbola.
