Hi there,
Apologize in advance if this is not the correct place to post my query. I've been googling didn't get it or maybe my input search parameter is not sufficient or irrelevant.
I am recently doing my graduate in physics and my inclination towards computational physics makes me to do my...
I've two questions here:-
1) Sound reflects it is said using laws of reflection of light.So,it means we hear max. sound when angle of incidence is equal to angle of reflection,right?& if not equal then what do we hear or not?
I guess we hear lesser than max.sound when the angles are not equal...
How to determine rarer & denser medium for light?
As i read in one book, it's written that denser medium & rarer medium for doesn't depend upon density.For eg. steam has less density than dry air but the steam is denser medium & dry air is rarer medium for light.Before this i used to think in...
1)We know this limit doesn't
\lim_{x\rightarrow-\frac{2}{3}}\frac{2}{2+3x} exists
after substituting the value ot that gives us answer infinity.But how about doing derivative at both numerator and denominator that gives us answer to 0.I guess this is not the correct way since I'ven't used the...
I think I have corrected your LaTex properly. sin(x- y)= sin(x)cos(y)- cos(x)sin(y) and you appear to be trying to put the numerator in that form. (It would be a good idea to explain things like that when asking about a problem.) You wind up with two parts:
\frac{sin x cos y- cos x sin y}{x-...
\lim_{x\rightarrowy}\frac{sin{x}-sin{y}}{x-y}
so this is the question.
I'm here solving this problem you please check where am i wrong or next idea I've to use here.
=\lim_{x\rightarrowy}\frac{sin{x}-sin{y}}{x-y}*\frac{cos{x}+cos{y}}{cos{x}+cos{y}}...
\lim_{x\rightarrowy}\frac{sin{x}-sin{y}}{x-y}
so this is the question.

For the 2nd question i.e \lim_{x\rightarrow0}(tan{x}-sin{x})
1stly i find its derivative [on both sides numerator and denominator] i got,
\frac{1-cos^3{x}}{3x^2cos^2{x}}
After further simplification with this i can't reach to the final answer.
Again on next way i change the trigonometric terms...
Yea i know tht hallsofivy actually tht was my true mistake because i was just trying using latex & i can't get it well.
actually.the process I'm going to do is tht for the question
(\sqrt{3x}-\sqrt{x-5})
is...
I multiplied it by conjugate on both denominator and numerator sides & i got...
thanks office_shredder i got the idea to use latex.
Actually,for 1st question, i tried is a bit different one but similar to tht ones.The above questions seems complicated rather than i did.I gave yo because i get more idea to solve the question i tried.
Ok the question is [similar to tht one]...
Yea you both are right so that i can catch where my mistake is but it's so tough to write mathematical notations overhere.Could you please give me a hint how can i write the mathematical notations?
lim sq.rt x[sqrt x - sqrt (x-a)] x-->infinity
I'm whacked outta solving these problems just hanging around for more than 2 hours for each question but can't solve it.I think it's out of my capability.LOL.
I hope you will solve these problems.I need your help.The questions are...
1) lim...
