Don't be sorry at allIm sorry i forgot where the x tends to go :/
lim (x-> 1) sqrt (x+3) - 2 /4x - 4
lim (x->0) 1- sqrt (cosx) / x^2
and im so sorry taking your time but i get so confused with limits .
You're doing them "the long way", which is fine just longer. I'll do the first one the way you started it though to get the answerWelll thank you sir![]()
Yes we used the hospital rule and well i did some shortcuts at both of them but the book solution it doesnt coincides with my solution.
It happens. We all make mistakes like this. Just have to learn from them. You are doing really well though because you knew that you would have to cancel something in order to solve the problem, which is the key idea with these "indeterminate forms". Someone else is replying to this thread now, so I'll won't comment on #2 yet.Than you sir yes i solved it and it is 1/16
my mistake its that i did in this way 4(x - 4/x) :/
