Translation for "ketjukäyrän" to english
Translation examples
Lisäksi hän opetti Warren Roeblingille edistynyttä matematiikkaa, kuten ketjukäyriä, lujuusoppia, rasitusanalyysejä, sillan mittoja ja vaijerirakenteita.
Emily Warren Roebling understood higher mathematics, calculations of catenary curves, strengths of materials, bridge specifications, and intricacies of cable construction.
Ketjukäyrän yhtälö on y = a cosh ⁡ ( x a ) = a 2 ( e x / a + e − x / a ) {\displaystyle y=a\,\cosh \left({x \over a}\right)={a \over 2}\,\left(e^{x/a}+e^{-x/a}\right)} , missä cosh {\displaystyle \cosh } merkitsee hyperbolista kosinia.
The equation of a catenary in Cartesian coordinates has the form y = a cosh ⁡ ( x a ) = a ( e x a + e − x a ) 2 {\displaystyle y=a\cosh \left({\frac {x}{a}}\right)={\frac {a\left(e^{\frac {x}{a}}+e^{-{\frac {x}{a}}}\right)}{2}}} where cosh is the hyperbolic cosine function.
