1) lim (5-sqrt[4+3x]) / (7-x), x going toward 7
2) lim (tan9x) / (1-cos7x), x going toward 0
3) lim (5sqrt[x]-2) / (x-32), x going toward 32, and the 5 is part of the radical so i guess its x^(1/5)
Hello,
Multiply by
then use identity to simplify the top =)
2) lim (tan9x) / (1-cos7x), x going toward 0
These should be known limits :/
3) lim (5sqrt[x]-2) / (x-32), x going toward 32, and the 5 is part of the radical so i guess its x^(1/5)
You can note that
And in general,
(here is what I've done about this formula : http://www.mathhelpforum.com/math-he...484-k-b-k.html)
