You are highly encouraged to use LaTeX to type your homework, but it is not required.
You'll need to install two things to write LaTeX on your computer: a TeX distribution, and an editor. Articles about installation can be found for Windows, Macintosh, and Linux. To typeset LaTeX without installing anything, try TeXonWeb or find an equivalent online program.
Googling around will give you more information that you could hope to use about LaTeX. Here's a video that gets you started from the very beginning, and here's a list of resources for beginners. Julia Gordon, who also teaches Math 220, has a list of resources here.
For the clarity of a LaTeX paper, without learning any code, you can also try LyX.
A large part of learning code is looking at what other peope have written. Provided for you is an extremely basic template for Homework 1, and a slightlier fancier version, based on a template by Prof. Andrew Rechnitzer.
If you'd like to see how I wrote something on my slides, take a look at the source files: 1Sets.tex, 2Sets.tex, 3Logic.tex, 4Proofs.tex, 5ContrapositiveProofs.tex, 6Contradiction.tex , 7Nonconditional.tex , or 8SetProofs.tex. (I might not be updating these source files, so they might diverge slightly from the pdfs listed above.)
If at least half of your assignments are typeset in LaTeX, you will get 1% added to your final mark. You do not have to use LaTeX for pictures to get this mark--you can leave space and draw them in by hand, or use another program to generate digital images that you include in your otherwise-TeX'd homework.
If you have questions related to your major, like which flavour of calculus you should be taking, OR if you have a major life event that might prevent you from completing the semester, you should talk to your faculty advisor.
UBC provides services to address, among other things: illness and injury, mental health and wellbeing, sexual assault (for people of all genders), other violence, discrimination and harrassment, diversity, disability, and ongoing medical considerations. If you have legal issues, you might be able to get help from the Law Students' Legal Advice Program. The Office of Equity and Inclusion is a good place to go if you want more information about maintaining an environment that is respectful, especially with regards to interculturality, LGBT*QIA status, race, students who are parents, etc. The Office of Access and Diversity provides disability support.
If something comes up during the semester that interferes with your academic progress (such as an illness, or caring for a loved one) contact your faculty advising office as soon as possible. You can find them here.
The province has an excellent website with information on mental health, including an online screening tool and resources: Here To Help. The Vancouver Access & Assessment Centre (AAC) is a point of entry for concerns about mental health and substance abuse, and they also have a call line if you just want to talk to someone. The BC Crisis Centre also has phone services for someone to talk to if you are in crisis.
Education is a tool for a better life, from increased earning potential to a heightened appreciation for the beauty and complexity in the world. Your real life extends far beyond the boundaries of this campus. It's important that you don't let your education interfere with your physical or emotional health.
If it isn't feasible to change the thing that's bothering you, we still might be able to come up with strategies for addressing it. At the very least, you can get an explanation of why things are the way they are.
