用implicit differentiation求得:y’ = 1/cos y 精彩部分:进一步转化为:y’ = 1/√[1-(sin y)^2] 而sin y = x,因此,(sin y)^2 = x^2, 解出:y’ = 1/√(1-x^2) 书本内容: 第一,书本对反函数进行了进一步的解释(补充高中知识欠缺的我)。 Theorem 5.6 Reflective property of inverse functi...
The balance between T helper type 1 (TH1) cells and other TH cells is critical for antiviral and anti-tumour responses1,2,3, but how this balance is achieved remains poorly understood. Here we dissected the dynamic regulation of TH1 cell differentiation during in vitro polarization, and during...

A technique often helpful in computing the derivatives of a differentiable function ƒ(x); setg(x) = log ƒ(x) where ƒ(x) ≠ 0, theng′(x) = ƒ′(x)/ ƒ(x), and if there is some other way to findg′(x), then one also finds ƒ′(x). ...
Rapid differentiation of homeologous chromosomes in newly-formed allopolyploid wheat - Ozkan, AA, et al. - 2002 () Citation Context ..., 2007). Fragments of DNA seem to have been lost through homoeologous recombination in synthetic allopolyploids (Liu et al., 1998; Ozkan and Feldman, 2001...
or [(g1(x) g2(x) g3(x) ….) / (h1(x) h2(x) h3(x) ….)A function of the form [f(x)]g(x) where f and g are both derivable, it is better to take the logarithm of the function first and then differentiate. Or, we can write it as y = (f(x))g(x) = e g(x...
We do not have a formula that gives antiderivative of logx. Here we can substitute,logx=tDifferentiating both sides of this equation gives,ddx(logx)=ddx(t)⇒1x=dtdx⇒dxx=dtMaking this substitution changes the integral to...
