Ac23 - Study guides, Revision notes & Summaries

Here is the full summary of notes and information for unit 3 criminology - crime scene to courtroom, containing everything from 1.1 - 3.2. These notes and information allowed me to achieve an A grade during the final controlled assessment. These documents will also benefit you when preparing for the unit 4 exam, crime and punishment.

y=sqrt(x) y=x^2 parabola y=x^3 cubic function y=|x| absolute value function y=cos(x) periods of 2pi y=sin(x) periods of 2pi y=e^x y=lnx

∫1/(a^2 + x^2)dx(1/a)arctan(x/a) Horizontal Tangent Linesdy/dt = 0, dx/dt /= 0 cos^2(x) (half angle)½(1+cos2x) How do you find the equation of a tangent line?Find slope, find point, plug into (y - a) = m (x - b) Vertical Tangent Linesdy/dt /= 0, dx/dt = 0 sinxcosx

Integration By Parts uv - ∫ v du, u = LIPET ∫ sin^m(x)cos^n(x) dx n or m is odd u-sub ∫ sin^m(x)cos^n(x) dx n and m is even half-angle formula sin^2(x) (1 - cos2x) / 2 cos^2(x) (1 + cos2x) / 2 ∫ tan^m(x)sec^n(x) dx m and n are even save pair sec(x)tan(x)

What is the formula for integration by parts? Integral of udv = uv - integral of vdu What is typically the best choice for U? Log, inverse trig What is typically the best choice for DV? Trig, exponential What is the priority list for by parts? LIATE What does L in LIATE mean? Log What does I in LIATE mean? Inverse trig What does A in LIATE mean? Algebraic

f(x) + c transformation up f(x) - c transformation down f(x+c) transformation left f(x-c) transformation right cf(x) -if c is greater than 1, vertical stretch - if c is between 0 & 1, vertical compression f(cx) -if c is greater than 1, horizontal compression -if c is between 0 & 1, horizontal stretch -f(x) reflection over x-axis
