DNA, tRNA and mRNA are all essential macromolecular biological molecules involved in genetics and protein production. The two major categories of genetic molecules are DNA and RNA, with both tRNA and mRNA...

The first step is deciding on the method of integration. For this integral it makes the most sense to use substitution.Let u = x² + 1Differentiate w.r.t x => du/dx = 2xRearrange for dx=> ...

Integrate by parts:u = ln(x) u' = 1/x v' = 1 v = xBy parts formula: uv - ∫u'v dx Therefore we have: xln(x) - ∫x1/x dx = xln(x) - ∫1 dx = xln(x) - x (+c)

If you have studied Physics, you may be familiar with the small angle approximation cos θ ≈ 1 - θ²  / 2. This is a surprisingly accurate approximation for small values of theta (try it!), but w...

Dans Entre les Murs le système scolaire est présenté dans une manière très négative à cause du fait qu’il échoue tous les élèves dans le collège. C’est vrai qu’il y a des élèves très faible dans ...
