How do you find the limit of x/sinx as x approaches 0? | Socratic
2016年3月3日 · The answer above that uses the limit #lim_{x rarr 0} {sin x}/x# also is invalid (using the criteria indicated by the note) because this limit cited needs also L'Hôpital's rule to be improved. It is not correct to say that is an important limit and that is why we must know if we can not prove it in the context that is intended for use.
What is the limit of sinx / x as x goes to infinity? - Socratic
2015年9月28日 · What happens to our function when #x# balloons up?. No matter what the input, #sinx# just oscillates between #0# and #1#.
How do you graph y=(sinx)/x? - Socratic
2015年4月19日 · We know that the limit in 0 is 1 (it's one of the notables limits: in a neighbourhood of 0 sin(x)=x+o(x^2) => sin(x)/x = 1+o(x) -> 1 if x->0 ) We know it is an even function (quotient of two odd functions), so the graph must be symmetric. We concentrate on x>0, and then extend by symmetry We know it has zeros where sin(x) has zeros (except for x=0) so it has zeros in x=kpi, k != 0. Then we ...
How can Sine Integrals be calculated using polynomial …
2005年2月24日 · du = 1/x dv = sinx v = -cosx u get -cosx/x + (integral of cosxlnx) ----- do integration by parts again u = lnx du = 1/x dv = cosx v = sinx so u get lnxsinx - (integral of sinx/x). add the (integral of sinx/x) over. So now you have 2(integral of sinx/x) = -cosx/x + lnxsinx divide the 2 over n you get -cos(x)(1/2x) + (1/2)ln(x)sin(x) +c
What is the derivative of sin(x)/x? - Socratic
2016年6月14日 · To find the derivative of a function in the form #f(x)/g(x)#, use the quotient rule:. #d/dx(f(x)/g(x))=(f^'(x)g(x)-g^'(x)f(x))/(g(x))^2#

What is the derivative of sinx/x? + Example - Socratic
2015年5月30日 · Let f(x)=sin(x)/x. Use your calculator to graph this over some window near x=0. You'll see that the graph has no vertical asymptote, in spite of the fact that the function is undefined at x=0. In fact, you should see that lim_{x->0}f(x)=1.
Translating Sine and Cosine Functions - Trigonometry - Socratic
Graphing #y=sinx+k# Which is the same as #y=k+sinx#: In this case we start with a number (or angle) #x#. We find the sine of #x#, which will be a number between #-1# and #1#. The after that, we get #y# by adding #k#. (Remember that #k# could be negative.) This gives us a final #y# value betwee #-1+k# and #1+k#.
