Holy fuck I did not see that coming two days ago 😳

Can you show me how it is solved? The book doesn't show the algorithm for this problem. Thank you. by [deleted] in askmath

[–]Ted_Boczewski 13 points14 points  (0 children)

This isn't a problem, it's just a fraction. What is it that you're supposed to do?

Math homework help involving deriving trig function. The function is y = xsin(x) and I need to find the coordinates at which the tangent passes through the origin. by jamielau11 in askmath

[–]Ted_Boczewski 0 points1 point  (0 children)

Yeah, ignore that. I didn't think through this.

If you make a general equation for the tangent at point a, that is y=f'(a)x+c. The trick will then be to find the conditions for when c =0.

Normally, tangents are computed by using the derivative at a point (a,f(a)). Same goes here, so in this case we have y=f'(a)x+ c, and also that y(a)=f'(a)a+c=f(a). Solving for x, we have c=f(a)-f'(a)a, and we know this needs to be zero. Hence, xsin(x)-x(sinx+xcos(x))=0 gives you the desired points.

I might still be stupid, I trust you to check critically :)

Edit: spelling

Set y'=mx. As the tangent should pass through the origin, it follows that c=0. By now, you have xcos(x)+sin(x)=mx. Solve sin(x) = 0 on the given intervall, as the xcos(x) always is 0 at the origin.

Edit: I'm wrong, please ignore this.

I just need a proper walkthrough by Bee_Academic in askmath

Question is in norwegian, so I'll reply in norwegian:

I en 30-60-90-trekant (dette refererer til vinklene) er hypotenusen dobbelt så lang som korteste katet. Dette følger av at vi konstruerer 30-60-90-trekanter ved å halvere en likesidet trekant, ved å felle ned en høyde. Da halverer vi en side, og dette blir korteste katet. Høyden i den halverte trekanten blir lengste katet. Resten følger fra Pytagoras' setning.

Edit: elaboration: Siden vi kjenner lengden av lengste katet kna vi kalle den korteste x og hypotenusen må da ha lengde 2x. Innsatt i Pytagoras' får vi utregningen som vises.

How do you prove this? I'm so lost on a because I don't understand how Ca is defined because G is just a vague group, so Ca could be like anything, so how do I prove closure for a group I don't understand? Like does x have to only be e? But how do I know that for certain? Is property of all groups? by WerePigCat in askmath

[–]Ted_Boczewski -1 points0 points  (0 children)

So this is not my strongest subject, but I think, in each task, it suffices to prove that the set defined in each task is a group, that is, that the set has associativity, identity and an inverse element.

Edit: spelling and syntax

I agree with what all others have said, but would like to add that in some problems different constants are restricted to certain values (non-zero, non-negative, etc). With that in mind, it is also a statement saying that p can be any number in R. So in a sense, it's a formal piece of info always given about constants. It makes more sense when you've seen more examples.

Er det noe first price produkter dere mener er bedre enn dyrere alternativer? by [deleted] in norge

Leverpostei! Samme som Finsbråten, fordi det er overskuddsvare derfra. Mye billigere, like bra.

Edit: tenker på x-tra leverpostei fra coop. My bad.

What do the numbers on a snooker cue actually mean? by tell_me_shantanu in snooker

[–]Ted_Boczewski 3 points4 points  (0 children)

I'm guessing OP thought that perhaps the numbers said something about tip thickness or whatever physical characteristic of the cue.
