Frequently asked questions

What background do I need?

For calculus explainers, you should be able to work with functions, graphs, and algebra. For linear algebra, you should be comfortable adding vectors and scaling them. Probability pages assume you can read a fraction as a share of a whole. You do not need a university affiliation.

If a page feels early, use the pathways or the matching topic pillar. The glossary is there for single words that stall a paragraph.

How should I use this site?

A reliable loop is: pick one idea, read the explainer once without rushing, say the claim out loud in your own words, then follow two or three internal links. Calculators come after that, as a check on a number you already understand.

The home page Start here strip is a five step on ramp if you are new. Explainers are the long reads. Topics are maps.

Do the calculators replace understanding?

No. Every tool on the calculators hub runs locally in your browser and returns a numerical estimate. A slope estimate is not a derivative proof. A Riemann sum is not an antiderivative. Use tools to test a guess or to see a number move. Then return to the definition.

Courses that ban computer algebra still expect you to write steps. These tools are educational probes, not an answer key. See the disclaimer.

Is the writing original? How do citations work?

The prose, examples, and teaching order are original to Higher Math Guide. We do not paste textbook pages or other websites. When a standard theorem appears, we explain it in our own words and link a reputable source so you can verify the claim.

The sources directory lists open courseware and references used across the site. If a citation is stale or a statement looks off, use Contact and say which page.

Who is this for?

This site is for students in a first serious pass at calculus, linear algebra, probability, differential equations, or proof habits. It also helps returning learners who want a calm second explanation. It is not written as exam prep from a specific board, and it is not a private tutor.

Joshua Israel Ventures LLC publishes the project as a free educational resource. Read About for mission and policy.

Is there a fee, an ad, or a product to buy?

No. Pages are free. There is no AdSense block, no affiliate layer, and no paid course upsell. The conversion we care about is a clear question or a topic suggestion, if you choose to write.

What happens if I write to you?

The contact form sends your name, email, and message to joshuaofisrael@gmail.com. The subject is [Contact: highermathguide.com] New message. After the form sends, a short confirmation says the note is on its way. Replies usually come within a few business days when volume allows.

This is not a homework hotline. We may point you to a page rather than solve a full assignment. That keeps the resource honest and usable for everyone.

Can I suggest a topic?

Yes. If an idea is missing, or a page should go deeper, send a short note. Name the course context if you have one, such as a first multivariable course or a series unit. Use the contact page.
