The answer is ==2/(x1)^2 This is a ratio of polynomials The derivative is (u/v)'=(u'vuv')/(v^2) Here, u=x1, =>, u'=1 v=x1, =>, v'=1 So, dy/dx=(1*(x1)1(x1Simply draw a right triangle We want an angle (call it A) of this triangle to be arcsin(x) For that to happen, the triangle might have hypotenuse c = 1 and side opposite the Compute \arcsin x \arctan \frac {\sqrt {1x^2}} {x} Compute arcsinx arctan x1−x2 https//mathstackexchangecom/q/Tabelle einfacher Ableitungs und Stammfunktionen (Grundintegrale) Diese Tabelle ist zweispaltig aufgebaut In der linken Spalte steht eine Funktion, in der rechten Spalte eine Stammfunktion dieser Funktion Die Funktion in der linken Spalte ist somit die Ableitung der Funktion in der rechten Spalte Hinweise Wenn
V a r ( X n) = 1 for all n But V a r ( 1 X n) approaches zero as n goes to infinity V a r ( 1 X n) = ( 05 ( 1 n 1 − 1 n − 1)) 2 This example uses the fact that V a r ( X) is invariant under translations of X, but V a r ( 1 X) is not But even if we assume E ( X) = 0, we can't compute V a r ( 1 X) Let Taylor expansion of f(x)= log (x1) at x=0, can be worked out as follows Answer link Related questionsThere's a simpler version of the above formula 1 ( 1 − x) n = ∑ k = 0 ∞ ( k n − 1 n − 1) x k You can prove this by induction differentiate and then divide by n Share answered Jan 24 '16 at 1505 Thomas Andrews
sec(tan^(1)(x))=sqrt(x^21) sec(tan^(1)(x)) let y=tan^(1)(x) x=tan(y) x=sin(y)/cos(y) x^2=sin(y)^2/cos(y)^2 x^21=(cancel(cos(y)^2sin(y)^2)^(=1))/cos(y)^2 x^21 The first term of the multiplier will be 1, in order to get 1 when multiplied, so add that to the right hand side 1 = (1x)(1 When x is multiplied by 1 it will give us x to cancel out So the next term on the right hand side is x 1 = (1x)(1x When x is multiplied by x it will give us x^2 to cancel out So the next term on the right hand side is x^2 1 = (1x)(1xx^2 Continuing in this way, we get 1 = (1x)(1xx^2x^3x^4) So 1/(1x) = 1xx^2x^3xIn mathematics, the Taylor series of a function is an infinite sum of terms that are expressed in terms of the function's derivatives at a single point For most common functions, the function and the sum of its Taylor series are equal near this point Taylor's series are named after Brook Taylor, who introduced them in 1715 If zero is the point where the derivatives are considered, a Taylor

Calculus Limits Determining Limits Algebraically 1 Answer foriteration 0 x == 1 foriteration 1 x == 2 foriteration 2 x == 3 So in this latter version you could use x as an index into the list iter_obj = my_listx Alternatively, a slightly more pythonic version if you still need the iteration index (eg for the "count" of the current object), you could use enumerate for (i, x) in enumerate(my_list1) # i is the 0based index into theA second, slightly different way of approaching this is to consider the expression $$(1x)(1 x x^2 x^3 \cdots)$$ Using the distributive property one gets $$(1 x x^2 x^3 \cdots) (x x^2 x^3 \cdots)$$ and again everything cancels except the $1$ in the first pair of parentheses, so $$(1x)(1 x x^2 x^3 \cdots) = 1$$ from which the desired conclusion follows
