GCSE数学公式 GCSE数学 GCSE培训机构

在数学课程学习和考试中，公式的运用是非常普遍也是非常重要的，今天易伯华未来小编带大家来解析AQA考试局考试大纲中所列举的一些常见GCSE数学公式，大家可以根据本文的列举分类进行这些公式的了解和掌握，一起来了解一下吧！学生应了解科目内容中包含的下列公式；考试中不会给出这些公式。The quadratic formulaThe solutions ofax2+bx+c=0, wherea≠0x=-b±√(b2-4ac)2aCircumference and area of a circleWhereris the radius anddis the diameter:Circumference of a circle =2πr=πdArea of a circle =πr2Pythagoras’ theoremIn any right-angled triangle wherea,bandcare lengths of the sides andcis the hypotenuse:a2+b2=c2Trigonometry formulaeIn any right-angled triangleABCwherea,bandcare lengths of the sides andcis the hypotenuse:sinA=ac,cosA=bc,tanA=abInanytriangleABCwherea,bandcare lengths of the sides:sine rule:asinA=bsinB=csinCcosine rule:a2=b2+c2-2bccosAArea =12absinC2. 学生应该知道下列公式或能够推导出这些公式；考试中不会给出这些公式。Perimeter, area, surface area and volume formulaeWhereaandbare the lengths of the parallel sides andhis their perpendicular separation:Area of a trapezium =12(a+b)hVolume of a prism = area of cross section x lengthCompound interestWherePis the principal amount,ris the interest rate over a given period andnis number of times that the interest is compounded:Total accrued =P(1+r100)nProbabilityWhereP(A)is the probability of outcomeAandP(B)is the probability of outcomeB:P(AorB)=P(A)+P(B)-P(AandB)P(AandB)=P(AgivenB)P(B)3. 学生不需要记住以下公式；考试将在相关问题中给出。Perimeter, area, surface area and volume formulaeWhereris the radius of the sphere or cone,lis the slant height of a cone andhis the perpendicular height of a cone:Curved surface area of a cone =πrlSurface area of a sphere =4πr2Volume of a sphere =43πr3
