Homework Statement \\int{\\frac{e^x}{x^2}dx} Homework Equations Integration by substitution Integration by parts: \\int{u\\ dv}=uv\\ -\\ \\int{v\\ du} The Attempt at a Solution Since it was clear that integration by substitution would not work, I tried integration by parts This is a typical transcendental equation which one solves using the Lambert function. So what we need to do is to change the form of this equation in a manner which is identical to [math]f(x)= x e^x[/math], and get the solution through [math]x= W How do you solve #e^x=2#? Precalculus Properties of Logarithmic Functions Natural Logs. 1 Answer Jim G.

Furthermore we can compute the variance with $$\text{Var}[X]=\Bbb E[X^2]-\Bbb E^2[X].$$ In general we can apply functions to random variables like $$\Bbb E[f(X)] = \sum_{x\in W_X}f(x)\cdot\Pr[X=x]$$ without considering that there are some cases where this rule does not apply.

Then add the square of \frac{f}{2}-1 to both sides of the equation. This step makes the left hand side of the equation a perfect square. Free simplify calculator - simplify algebraic expressions step-by-step Here integral [math]\int e^x \frac{x^2+1}{(x+1)^2}dx.[/math] By converting to a Integral of the form [math]\int e^x\left[f(x)+f’(x)\right]dx.= e^xf(x)+c[/math] Adding and subtracting 1 in the numerator and split writing of given integral and follo For a random variable X, the variance is defined as: Var(X) = E[(X-E[X])^2]. Thus, Var(X) = E[(X^2 - 2XE[X] - (E[X])^2].

Share. Cite. Follow Apr 05, 2011 · e^x * e^x = e^(x+x) = e^(2x) The exponent rule here is: a^b * a^c = a^(b+c) You could also apply this rule: (a^b)^c = a^(bc) e^x * e^x = [e^x]^2 = e^(2x) Details:-e^x * e^x = -(e^x * e^x) = -e^(2x). The minus sign doesn't change anything. It just gets multiplied by the rest of the calculation.

If you graph y = e^x - x then e^x-x=0 when y=0 ( y=0 is the x axis) For example, suppose X is a discrete random variable with values x i and corresponding probabilities p i. Now consider a weightless rod on which are placed weights, at locations x i along the rod and having masses p i (whose sum is one).
