Trying to solve it without using L'Hôpital's Rule

  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations
  2. Do not ping the mods, unless someone is breaking the rules.
  3. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Derivate

#

Oh

pale shore
#

What?

cosmic lava
#

I was suggesting using the literal definition of derivation

#

The derivative is the limit at a given point

#

But you cannot use l'hospital rules

pale shore
#

yeah I mentioned that and I already used l' "hospital" rule and got the answer but I can not use it to solve

#

thanks for helping though

cosmic lava
#

What hypothesis do you have ?

#

Factorisation ?

pale shore
#

nope

cosmic lava
#

Let me get into it

pale shore
#

I guess multiplying by the conjugates of the numerator once and the denominator

cosmic lava
#

I wzs literally writing that

#

Lol

#

Conjugate

#

You was faster

pale shore
#

haha yeah I was having it on my mind earlier but I said why not to seek for some help

#

lemme try it and see

cosmic lava
#

Send it i am interested

pale shore
#

the thing is i got other limits probs that i cant solve with l'hopital's

@cosmic lava

ay man srry for late but im still a latex beginner

,tex $\lim_{x\to 1}\frac{\sqrt{2x-1}-1}{\sqrt{3x+1}-2} \[0.5cm] \frac{\sqrt{2x-1}-1}{\sqrt{3x+1}-2} \cdot \frac{\sqrt{2x-1}+1}{\sqrt{2x-1}+1} \cdot \frac{\sqrt{3x+1}+2}{\sqrt{3x+1}+2}$ \ Evaluating all this results in $\frac{(2x-2)\cdot \sqrt{3x+1}+2}{(3x-3)\cdot \sqrt{2x-1}+1} = \frac{2(x-1)\cdot \sqrt{3x+1}+2}{3(x-1)\cdot \sqrt{2x-1}+1} = \frac{2 \cdot \sqrt{3x+1}+2}{3 \cdot \sqrt{2x-1}+1 }$ \ Then plotting one will give us $\frac{4}{3}$

Fuck wolfram

pale shore
cosmic lava
#

Cant use that

#

?

pale shore
#

i only get to use one formula

#

$lim_{x\to a} \frac{x^{m}-a^{n}}{x^{m}-a^{n}}=\frac{m}{n} \cdot a^{m-n}$

i dont even know what this formula called and i tried to search online i found nothing
