Nice try Schlomo

Anyone who has taken a class in Differential Equations, could you confirm if the answer in green makes sense?

This section is on series solutions for linear equations

@ButMomShesA300YearOldLoliVampire yes the way you solved it up to the green circle is correct. Now the question asks for you to find two linearly independent solutions. In the green circle you see that after you specify `C_0` and `C_1` that all the other coefficients of a solution are determined. So for one solution choose `C_0 = 1` and `C_1 = 0`, and for the other solution choose `C_0 = 0` and `C_1 = 1`. These solutions are linearly independent since no scalar multiple times the `C_0` and `C_1` of one solution will ever give you the `C_0` and `C_1` of the other solution.

@ThisIsChris Thanks a ton!

@ButMomShesA300YearOldLoliVampire you're welcome!

@Warren H Better to just post your question.

Working on graphing linear equations in two variables (x and y).

And the line I have to graph is 5y=9

I put it in a graphing calculator and came back with a straight line (0,0) which is incorrect as the problem is asking for two coordinates for x and y

If theres no x in the equation it will be a straight line. Y = 9/5

@Warren H

@Warren H To add to @Deleted User 's response, you can rewrite `y = 9/5` as `y = 0x + 9/5`. Remember line formula is `y = (slope of line)x + (y-intercept)`. So for @Deleted User 's formula you have a slope of zero (i.e. a flat line) and a y-intercept of 9/5.

So the answer I came back with is 0, 1.8

But the computer program I have to do my homework on requires me to answer the x coordinate and it will not accept 0. Very weird

@ThisIsChris @ChillS

@Warren H hmm, how exactly is the question phrased? Do you have a screenshot?

Oh you need to enter something for B as well, any other point on the line will do. (They say enter two points because two points determine a straight line). You can enter any other point from the line, for example (1, 1.8)

Ohhh okay. That seemed to have worked. Is this the case whenever there is a straight line?

@Warren H yep!

This program drives me nuts

I just got another answer wrong for writing it in decimal numbers but it was counted as wrong because the answer was in fractions. Did the math calculation, and the fractions converted into the decimal coordinates that I entered.

Do you have a screenshot? I wonder if there's something specific in their question phrasing that indicates they want fractions instead of decimals.

It did not. It just said "Find the y-intercept and x-intercept of the following linear equation."

That's so weird, so for the y-intercept, they rejected 7.5 as the y-intercept? That's so weird because *they* give you the equation in decimal!

oh woops sorry that was the next problem

the one they flagged wrong was the coordinate points -4.8 and -0.375

they said those were incorrect and that the right answer was -24/5 and -3/8 which are the exact same numbers

@Warren H do you get points off for that? might want to bring it up with your professor in that case

Yes I did. I will for sure. If this was on a test and graded in that way I would have gotten the problem wrong

Hi. New to the server. If anyone needs help with any kind of research, I'm your goy. I have a lot of experience in it and I even enjoy it oddly enough. This extends out to school essays, work related, or even anything out of general curiosity. Any subject as long as I don't need a degree to grasp the basic concept. I can write you(within reason and with digression) any paper/article, and other kinds of research assignments. I also excel at photo shop. Advice and suggestions are free. Real work is cheap. DM me if you are interested.

Does anyone have any protips or suggestions on how to cultivate a better habit of doing homework/getting schoolwork done outside of class? All through normal school I was in the category of kids who didn't need to study and could get through homework during school hours without much difficulty, but now that I'm in college my grades are suffering because I don't have the habit/mindset of doing homework/studying outside of class. Anybody have experience with overcoming this?

@Gaius Mucius Scaevola Wake up early. 5:30-6. Go for a run. Then block 1-2 hours for homework. If it isn't done first thing, there won't be motivation left at the end of the day.
