Dumb moment here...I have the following equation:
Sin (4/(3x+3)) / Sin (4/3x)= 1
can i cancel out the sin's?
Sin (4/(3x+3)) / Sin (4/3x)= 1
can i cancel out the sin's?
No you can't just randomly cancel it out.Dumb moment here...I have the following equation:

As long as a isn't 0 you can do this:Dumb moment here...I have the following equation:

Isn't this equivalent toDumb moment here...I have the following equation:

The letters s-i-n in [itex]\sin(x)[/itex] are not variables. Those three letters together stand for an operation -- namely the operation of computing the sine of x. Similarly, we use the "+" symbol to refer to the operation of adding two values.Dumb moment here...I have the following equation:

Does this mean I can't do this...The letters s-i-n in [itex]\sin(x)[/itex] are not variables. Those three letters together stand for an operation -- namely the operation of computing the sine of x. Similarly, we use the "+" symbol to refer to the operation of adding two values.
"Canceling" is the notion of dividing out by a common nonzero number, or by a common variable that stands for a nonzero number. "sin" is not a variable; it is an operation. Canceling is not a matter of "deleting letters and symbols" that appear in both the numerator and denominator.
There this Wiki-link hereYeah, so funny... ;)
But if you want the limit, still can't cancel the sin's (cancel the sins... what would a priest think?) :P But you can do the obvious thing, try to substitute. You get sin(0)/sin(0) so, 0/0... why don't you try now L'Hôpital?
I'd also include Euclid, Newton, Leibniz, and Neumann on that list, but in general I think you're right. I still can't remember how to spell Ramananan, and he seems to have done everything he can with numbers.There this Wiki-link here
http://en.wikipedia.org/wiki/L'Hôpital's_rule
which gives some good examples on howto use L'Hospitals rule. Something which is a bit strange is that why is it to become a famous mathematician you have to so strange names? ;)
Only mathematician with a easy name to remember is Niels Henrik Abel and Cauchy.
:D Susanne

Yeah you are right.You know the sense of humour of physicists... so when you come up with an important equation, this thread will come up and they will call it the Susanniwitz equation, no matter what your wishes are by then! Sorry, darling, you're dooooomed! :) :) :)
The funny thing is I tested this problem on the equation-solver on old TI-92 and it claims that there are several solutions to the OP problem like the solutions are polynomial...Yeah, funny as it is the other discussion, let us focus, boys and girls, ok? :)
In this case, the limit does exist, the conditions on the theorem are met. Promised. The question poser has to work it out, though. (This is homework help.)
Your calculator is correct. Don't forget that if you have an equation of the type sin(x)=sin(y) then x=y+2pi*k is a solution for k an integer.The funny thing is I tested this problem on the equation-solver on old TI-92 and it claims that there are several solutions to the OP problem like the solutions are polynomial...
Okay,Your calculator is correct. Don't forget that if you have an equation of the type sin(x)=sin(y) then x=y+2pi*k is a solution for k an integer.
