university levels of education Calculus IV IV▊

Calculus IV, Deep Mastery Series — handmade, no ads, no sign-ups. Every lecture is kept whole and shown whole: nothing is summarised, so what you see is the lecture as it was written. 257,640 words across 120 lectures, from advanced integration to applied and computational calculus. Twenty-one ways through the same text, forty-six palettes on a white default with dark a click away, twelve layouts and colours you can set yourself. The mathematics is typeset from the author's own LaTeX, so every formula renders as written. Lectures 78 and 87 and 94 and 104 and 116 are the one gap; they were never in the source text, and the shelf says so rather than pretending otherwise.
