  1. 5.1 Calculus - SL content

    1. SL 5.1Limits and derivative concept

      • Estimate limits from tables or graphs; formal analytic limit methods are not required. • Interpret derivative as gradient function and rate of change. • Use notation dy/dx, f'(x), dV/dr and ds/dt.

    2. SL 5.2Increasing and decreasing functions

      • Interpret f'(x)>0, f'(x)=0 and f'(x)<0 graphically. • Identify intervals where functions are increasing or decreasing.

    3. SL 5.3Derivative of powers

      • Differentiate f(x)=ax^n to f'(x)=anx^(n-1), n in Z. • Differentiate sums of integer-power terms.

    4. SL 5.4Tangents and normals

      • Find tangents and normals at a given point and their equations. • Use analytic methods and technology.

    5. SL 5.5Integration as anti-differentiation

      • Integrate polynomial-type functions as anti-derivatives. • Use boundary conditions to determine constants. • Connect anti-derivatives, definite integrals and area under curves.

    6. SL 5.6Differentiation rules

      • Differentiate x^n (n in Q), sin x, cos x, e^x and ln x. • Use sum/multiple rules, chain rule, product rule and quotient rule.

    7. SL 5.7Second derivative and graph behaviour

      • Use second derivative notation d2y/dx2 and f''(x). • Relate graphs of f, f' and f''; use technology where useful.

    8. SL 5.8Extrema, optimization and inflexion

      • Find local maxima/minima using first-derivative sign changes or second derivative tests. • Solve optimization problems in contexts such as profit, area and volume. • Identify points of inflexion and concavity.

    9. SL 5.9Kinematics

      • Use displacement s, velocity v, acceleration a and total distance travelled. • v=ds/dt and a=dv/dt=d2s/dt2. • Displacement is integral of velocity; distance is integral of speed |v(t)|.

    10. SL 5.10Indefinite integration

      • Integrate x^n, sin x, cos x, 1/x and e^x. • Use composites with linear functions and reverse chain rule/substitution by inspection.

    11. SL 5.11Definite integrals and areas

      • Use definite integral analytically: integral_a^b g'(x) dx = g(b)-g(a). • Find areas under curves and between curves, accounting for sign. • Write correct integral expressions before calculating.
