What to Know:

  • It’s the second section of the ACT
  • 您有60分钟的时间限制
  • You will face 60 multiple choice questions
  • You get to use a calculator for the whole test (but it must be anapprovedone)

学习什么:

  • 基本形状的区域,体积和表面积的几何公式​​(与坐限不同,该行为不会给你这些!)
  • Multiple-choice math test strategies such as “backsolving” the problem using the answer choices, substituting in numbers, and estimating.
  • 预代数
    • decimals, fractions, integers, positive and negative numbers, square roots, scientific notation, factors, ratios, proportions, percents, charts and graphs of statistics
  • 基本代数
    • exponents, evaluating algebraic expressions through substitution, using variables to express relationships, algebraic operations, and factoring quadratic equations
  • Intermediate Algebra
    • 二次公式,理性和自由基表达,绝对值方程和不等式,序列和序列,方程式,二次不等式,功能,矩阵,多项式的根,概率和复数
  • Coordinate Geometry
    • evaluating points and lines on a graph, polynomials, circles and other curves, graphing inequalities, slope, parallel and perpendicular lines, distance, midpoints, and conics
  • 飞机几何
    • 垂直和平行线,圆圈,椭圆,矩形,三角形,平行四边形,梯形,变换,面积,体积,三维几何形状之间的角度和关系
  • 三角学(在非常基本的水平)
    • 三角性关系触发函数的直角,值和属性,使用Trig标识,求解Trig方程

What Not to Study:

  • 三角学超出了基础知识。但是,你应该知道:
    • SOH-CAH-TOA
    • 如何解决正确的三角形
    • the unit circle
    • TANθ= SINθ/COSθ
    • sin^2 θ + cos^2 θ = 1
    • 什么正弦,余弦和切线图看起来像
