calculiphysics and hydrostaticacoustic bandpass help?
welcome toWhere b-stock is the new a-stockTEAM WEST
Hey west need your help with using l'hospitals rule on yhe following indeterminate fx.
Problem: find the limit using l'hospitals rule, or another elementary method.
Fx = lim as x approaches infinity of x( sin π/x)
My attempt at the problem, f(inifinty) yields infinity times 0.
So, i can use the rule and take x/1/ (sin π/x ) to yield infin/infin as x approaches infin.
Then, i can take derivative of both num, and denom by l'hospitals rule.. ultimately i get 0
But thr answer is π
this post is gold.
every time I see 0 and L'hospital rule, I just assume infinity is the answer and vice versa
this might help, haven't done this since cal 2. my higher level engineering classes are kicking my butt this semester.
copy and paste from calculator lol
