Jul 11, 2020 · I know how to find the Taylor expansion of both $\sinh x$ and $\cosh x$, but how would you find the Taylor expansion of $\tanh x$. It seems you can't just divide both the Taylor …

I heard teachers say [cosh x] instead of saying "hyperbolic cosine of x". I also heard [sinch x] for "hyperboic sine of x". Is this correct? How would you pronounce tanh x? Instead of saying "

Feb 26, 2018 · The tanh function on the other hand, has a derivativ of up to 1.0, making the updates of W and b much larger. This makes the tanh function almost always better as an …

Generally speaking, $\tanh$ has two main advantages over a sigmoid function: It has a slightly bigger derivative than the sigmoid (at least for the area around 0), which helps it to cope a bit …

Assuming the numbers are stored in fixed point with an 8 bit fractional part then the approximation to $\tanh (x)$ should work to the limit implied by the resolution, or for arguments $\tanh^ {-1} …

Jan 29, 2018 · It is known that $$ \tan z=\operatorname {i}\tanh (\operatorname {i}z). $$ So, from the derivative polynomial of the tangent function $\tan z$, we can derive the derivative …

Dec 21, 2011 · The functions $\tanh x$ and $\arctan x$ have a similar graph. Is there a formula to transform $\tanh x$ to $\arctan x$?

Jan 6, 2017 · Is it possible to write $\tan^ {-1} (x)$ as a power expansion of $\tanh (x)$? I mean can we say this? $$\tan^ {-1} (x)=\sum^ {\infty}_ {i=0} \alpha_i \tanh^i (x)$$ The power series is …

Jun 3, 2015 · Another option is start with the Taylor series for the inverse function, artanh artanh, which is rather easier to derive, and use the Lagrange Inversion Formula to produce the …
