Evaluate the limit using L'Hospital's rule if necessary. lim as x goes to +infinity x^(6/x)

Calculus

Using L'Hopital's Rule, find the limit: lim x->0+ (as x approaches 0 from the right) of sinx/x^(1/3)

infinity of the summation n=1: (e^n)/(n!) [using the ratio test] my work so far: = lim (n->infinity) | [(e^n+1)/((n+1)!)] / [(e^n)/(n!)] | = lim (n->infinity) | [(e^n+1)/((n+1)!)] * [(n!)/(e^n)] | = lim (n->infinity) | ((e^n)(e^1)(n!)) / ((n+1)(n!)(e^n)) | ..the e^n...

Using the 4 step method fidn the derivative of F(x) =1/(x^2) 1) I got /(x^2+2xh+h^2) 2)2xh+h^2/(x^2+2xh+h^2)(x^2) 3)2x+h/(x^2+2xh+h^2)(x^2) 4)1/x I don't understand why I got this problem wrong on my test can you explain the correct way? The second step is wrong, it should be ...

Calculus

Let f be a function defined for all real numbers. Which of the following statements must be true about f? Which might be true? Which must be false? Justify your answers. (a) lim of f(x) as x approaches a = f(a) (b) If the lim of f(x)/x as x approaches 0 = 2, then f(0)=0. (c) ...
