Are you able to prove that (3w/sin3w)=1, because the only thing I could remember in my calculus class is to prove that (sinx/x)=1. Or do you take a resprocal of it?

(sin x) (x) = x sin x (sin x) (sin x) = sin^2 x So it should be limit of sinx/x as x approaches 0 times limit of sin x as x approaches 0. Though the answer is still 0, there’s a problem in the process. Thanks.

Since sin(x) using the unit circle equates to zero, and x is approaching zero (so you plug in zero), either way you write it will be multiplying by zero. I’ll admit I had to pause the video to think about it for a minute to completely understand what he meant but the way he wrote it is still technically viable.

I just don't see a pattern at all. It feels like he's explaining how to do the specific problems rather than teaching us how to analyze problems on our own. I'm gonna be solving all of these thinking I understand them then when the tests arrives I won't even be able to know where to start or how to tackle the problem.

There is a better way to approach the problem presented at 6:00, in case if anyone is confused by the arbitrary, "just switch the 5 and the 2." Instead of "just switching," multiply the numerator and the denominator by 2/5 to maintian a logical approach. In the denominator the 5's cancel out leaving a 2x, and just keep the 2/5 that pertains to the numerator on the outside as it was exemplified in the previous problem.
@scarleteyes415
@scarleteyes415 6 жыл бұрын
Very easy way to do it: Before multiplying anything, we have the fraction "sin(2x)/5x". Since the fraction is already divided by 5, we take 1/5 outside the limit, so the fraction becomes: 1/5 (lim sin2x/x). Now we just solve it like we did in the previous question, the only difference is that we have 1/5 outside the limit. We multiplay the equation by 2/2 and we get: 1/5 (lim 2sin2x/2x). Now we just take out the 2 in the numerator outside the limit the same as the previous question, hence it's multiplied by 1/5 that is also outside the limit: 2/5 (lim sin2x/2x). So, we put Y = 2x and we get: 2/5 (lim siny/y) as y goes to zero, so the latter term is equal to 1, therefore 2/5 (1) = 2/5

I agree, his methods are somewhat unorthodox to a logical approach to math, but it still works anyhow. Still, its better to have general logic in tackling these problems instead of just "switch these numbers" without knowing the reason why or how the value within the function should still remain the same while arranging the numbers, manipulating numbers isn't that simple.

if you're looking for why to use radian? then here's an explanation - In radian we use number, like the pie itself, π=3.1416... in degree which is equivalent to π radians=180° So, if you look into the function like sinx/x, in here x=some number; because lim(x→0) not x→0°. x does not mean degree of any angle...that's why we have to use radian.

guys u don’t need radian mode for it and easier way would be just writing pie as 180 and you’ll get it all. for example pie/2 is 90 degrees, u can simply just do 180/2 and you’ll get 90 or another example 2pie it’ll be 180 x 2 which would be 360 degrees or a harder example 3pie/2 u would simply do 3 x 180 which would be 540 then divide it by 2 and you’ll get 270. thank me later!

side question - where do you pull the 4/4 from at 11:27? i understand the tan 4x, but are we not multiplying by 3/3 because 3x got moved? what about x/x? the last problem made me think we had to use each independent variable. i'm a little confused on that.
@JKMath
@JKMath 2 жыл бұрын
The reason he switches to y is to show you that it is still a form of the same special limit. That step is not completely necessary in your work, but he does it anyway to remind you that it is a special limit that is equal to 1. So in the end, all you need to know is if you have the limit as x approaches zero of sin(x)/x where as long as whatever is inside sin is also in the denominator, the limit is equal to 1. Hope that clears things up for you!
@JKMath
@JKMath 2 жыл бұрын
@@mattmo8648 For your side question, what you need to know is that you are always allowed to multiply by a form of 1. Anything divided by itself is 1, and multiplying anything by 1 does not change that value. So, since 4/4 is just equal to 1, we can multiply it by the limit and that allows for the use of the special trig limit. We are not multiply by 3/3, instead the 3x in the denominator was just moved out so that it is easier to see where the special limit is located. So, when determining what form of one to multiply by, look inside of your trig function (in this case sin(4x) ), and whatever is inside, you want that to be in the denominator. That's why you multiply by 4/4, because then there will be a 4 in the denominator that is multiplied by x that can then be moved under sin(4x) to then create a form of the special limit. I hope this makes sense, if not (this can be difficult to describe with just words), feel free to check out my own tutorial video on this topic that is on my channel, I'll link it here for you. I have all kinds of calculus tutorials that you may find helpful! Here's the link: kzbin.info/www/bejne/gaDHnql6rqyNpqs

Loved this video it really helped me catch up in my calc classes- one problem near the end though, I'm pretty sure sin^2(x)/x does not equal sinx/x*x, it equals sinx/x*sinx, although the limit still comes out the same.

x*sinx/x you mean, but yeah limit comes out the same since sin(0)=0 and 0=0

I found the sin7x/sin3x strategy very helpful.

can someone explain why at 13:48 (sin^2 x)/x becomes (sinx)/x * x???

i think there was a mistake instead of sinx*sinx, you wrote sinx*x. Infact limit when x approaches 0 of sin^2(x)/x = 0

14:03 isn’t sinx • sinx not sinx •x

You are right, I believe he made a mistake. And if we follow along with that, sin(0) would equal 0 too(but keep in mind that cos(0) equals 1 so don't confuse them if another problem asks). So the final solution is still the same.
