<p>The Barron’s ACT book has a very in-depth math section. It covers topics such as composite numbers, the different properties, factoring trinomials and perfect square trinomials, the quadratic formula, imaginary numbers, matrices, identifying different conic figures from the formula, in-depth logs, the formulas for arithmetic and geometric sequences, binomials, proportions between similar triangles, surface area of strange figures, differences between secants and tangents, the measure of specific angles in a circle based on the arcs (like inscribed angles, central angles, angles formed by two tangents, etc.)–which they stress A LOT–and some crazy trig like coterminal angles, trig identities/equations, trig using nonright triangles, and more. </p>
<p>My question is whether it is worth it to review the entire section, or are these topics crazy and never seen on the ACT (I haven’t seen them on any practices I’ve done). I don’t want to waste my time, but if these topics come up and I should know them, I would like to study them.</p>
<p>Is it worth it? Thanks.</p>
