here are some questions that puzzles me on:
pi = the "pi" sign
sqrt. of = sqrt. of a number
infinity = infinity sign
1.) lim x->+infinity (x)^(2/ln(1+x^3))
2.) lim x->0^+ (cos sqrt of x)^(1/x)
3.) limx->1-0 ((2/pi)(arcsin(x)))^(1/acrcos(x))
4.) lim x->0^+ (x)^((1)/(1+ln sqrt. of x))
5.) lim x->+infinity (2+e^x)^(-1/x)
6.) lim x->0 (1+3x)^(2/sin(x))
7.) lim x->0 ((a^x+b^x+c^x)/(3))^(1/x)
well, I've already encounter and solve some limits but not related on these parts(fractions as exponents)
tried reading my book but didn't show some examples on how to solve it.
If you know how to solve it, please let me know.
or if you've got some examples,then show it to me.
And
thanks for your time!
