    Undergrad How Do I Calculate the Limit of Sin^-1X/X as X Approaches 0?

    Sry that i might post up silly question but i am still new to calculus ... How do i solve this ?? Lim X->0 Sin^-1X/X

    Undergrad Is Sin^-1 X = (Sin X ) ^ -1 ?from my book it stated :f(x) =

    agree with that ... when i tell some of my frens that Sin^-1 X =/= 1/Sin X , they feel shock too ...

    thanks ! want to make sure between the relationship with sin X and Sin ^-1 X ... =D

    Is Sin^-1 X = (Sin X ) ^ -1 ??from my book ... it stated :f(x) = Is Sin^-1 X = (Sin X ) ^ -1 ?? from my book ... it stated : f(x) = Sin ^-1 X f'(x) = 1/(1-X^2)^1/2 instead of f'(x) = -cot X / sin X Why is it so ?

    High School What is an unbiased estimator ?

    Thanks , i am still new here . since unbiased estimator = mean/paramete , we want it to be close to the mean for what purposes ??

    High School What is an unbiased estimator ?

    any sample that you draw will have noise in it, >---- what does the noise mean by ?? mean like a One-to-One function ??

    What is an unbiased estimator ?? I do not really understand what is an unbiased estimator during my statistic studies ~~ THANKS ~~
