Maybe I interpreted it differently

2021-02-14 23:51:09 UTC  

Think about it.

2021-02-14 23:51:34 UTC  

the fact is she is ugly and her feeling that way doesn't impact reality. But now I see where you were going

2021-02-14 23:51:43 UTC  

makes much more sense this way

2021-02-15 02:18:19 UTC  

big brain thinking right there

2021-02-15 05:32:32 UTC  

Can someone explain to my smooth brain why when I put in tan(30 in four different calculators I get two different answers

2021-02-15 05:35:26 UTC  

With Two TI-84s I get -6.4053
And on basic calculators like your PCs calculator I get .557

2021-02-15 05:43:02 UTC  

did you check what mode you have? degree or radian?

2021-02-15 05:43:59 UTC  

tan(30 degree) is .577

2021-02-15 05:44:12 UTC  

tan(30 RAD) is -6.405

2021-02-15 05:47:47 UTC  

Thank you I was in RAD not degree

2021-02-15 05:54:36 UTC  

When I signed up for this CNC class I didn't think I would have to know trig haha

2021-02-15 14:17:46 UTC  

Its worth noting that tan 30 degrees is 1 / root 3 in exact form

2021-02-15 14:17:58 UTC  

Not sure why people need exact form but that'll come in handy

2021-02-15 17:32:58 UTC  

Or root 3/3

2021-02-15 17:53:25 UTC  

Root 3 /3 is prob better because the denominator isn’t a radical

2021-02-15 19:04:32 UTC  

Is anyone here familiar with ode45 in matlab?

2021-02-15 21:28:10 UTC  

Before I changed the mode in my TI84 I did that 1/root 3 and got the answer I needed

2021-02-15 21:28:58 UTC  

Ode45 takes in initial conditions and x d_dot as a function
I don't remember if state space us requiered or not
It has been a while

2021-02-15 21:29:05 UTC  

ah I see

2021-02-15 21:29:18 UTC  

I didn't know how to change from exact to approx for a while

2021-02-15 22:46:27 UTC  

Does anyone know two numbers that multiply into -60 but add to positive 2?

2021-02-15 22:53:02 UTC  

it would be 2 linear equations

2021-02-15 22:53:08 UTC  

Aye but to solve it

2021-02-15 22:53:11 UTC  

I need to know that.

2021-02-15 22:53:15 UTC  

I have to know this

2021-02-15 22:53:25 UTC  

To factor it into the 2 linear equations.

2021-02-15 22:53:45 UTC  

Well you will have to declare 2 variables and have each represent a number

2021-02-15 22:53:45 UTC

2021-02-15 22:53:56 UTC  

4 times -15 is -60 yes

2021-02-15 22:53:57 UTC  

Oh factoring

2021-02-15 22:54:13 UTC  

And then you have to find two numbers that multiply into that sum

2021-02-15 22:54:24 UTC  

But add themselves into the middle number

2021-02-15 22:54:41 UTC  

And once you did that

2021-02-15 22:54:47 UTC  

You can factor it into the 2 equations.

2021-02-15 22:55:54 UTC  

I dont think its factor able

2021-02-15 22:56:13 UTC  

Alright I will just say that then

2021-02-15 22:56:23 UTC  

Yeah that should be the right answer

2021-02-15 22:56:43 UTC  

Yep that was the answer.
