Continuity: lim g x h a lim h x x a x a ? Differentiability: Continuity plus lim g x lim h x x a b 3) Area height dx , x a b Volume Area dx a a 4) Relative Max/Min of k x k x 0 or und (critical points) Max k changes from to Min k changes from to 5) Absolute Max/Min (max/min) of k x @ critical points or endpoints 6) Points of inflection of k x k x 0 or und and k changes sign b 7) Average value: f ave 1 f x dx b a a Application of average value: vave 8) Position-Velocity-Acceleration: b s b s a 1 v t dt ba a ba v t s t a t v t s t x 9) Initial condition formula: x0 , y0 , y x y0 y t dt x0 t Application t0 , s0 , s t s0 v x dx t0 v t dt s t c a t dt v t c 10) Distance- Displacement: b Dis tan ce v t dt area a b Displacement v t dt net signed area a 11) Fundamental Theorem of Calculus b f x dx f b f a a d dx f x h t dt h f x f x a 12) Given a graph of a function f, x and g x f t dt , then a g x f x make sign line here g x f x make sign line here dV dr , given and V r 2 h dt dt Find connection between r and h and substitute ( in cones look for similar triangles). Differentiate with respect to t. Don't forget the chain rule. V r 2 h, h 2r 13) Related rates: find Example: V r 2 2r 2 r 3 dV dr 2 3r 2 dt dt dy x 2 y 1 dx Solve: find y - separate variables, integrate both sides, only one c is necessary, use initial condition. If 2 branches, use the branch the contains the point given (initial value) 14) Slope fields: Slope field given- Trigonometry Functions sin Reciprocal functions 1 csc Functions in terms of sin & cos tan sec x cos sin cos 1 sec tan cot 1 cot cos sin csc x 1 sin x 1 cos x Cofunctions: sine – cosine, etc sin cos , cos sin 2 2 Negative functions sin sin (odd function) csc sec , sec csc 2 2 cos cos (even function) tan tan (odd function) tan cot , cot tan 2 2 Pythagorean Identities sin2 cos2 1 divide by sin2 1 cot 2 csc2 divide by cos2 tan 2 1 sec2 Cosine: Sum / Difference Cosine double angle cos cos cos sin sin cos 2 cos cos2 sin 2 Cosine Double angle Power reduction Half angle 1 cos 2 1 cos 2 substitute for cos2 cos 2 1 2sin 2 sin 2 sin 2 2 1 cos 2 substitute for sin 2 cos 2 2cos2 1 cos2 2 1 cos 2 cos 2 Sine: Sum / Difference Sine double angle sin 2 sin 2sin cos sin( ) sin cos sin cos 2 2 1.5 1 0.5 3 2 2 1 1 2 2 1.5 1 fx = sinx 1 3 2 gx = cosx 2 2 1 2 0.5 0 0 -0.5 -1 6 4 3 1 2 2 3 4 5 6 6 4 3 1 0 -0.5 -1 -1.5 -1.5 -2 -2 " " is a special # and 3.142 0 2 2 3 4 5 6 Exponential and Logarithmic Functions Exponential and logarithmic with the same base are inverse functions (reflect over the y x line) Exponential function: f x a x , Domain : x , Range : y 0 lim a x 0, lim a x x x Properties of Exponential functions: 4.5 an am an am a n a m a nm a a a b a n m an n 3.5 3 nm n m k fx = ex kn km b 2.5 2 1 an a a limxf is + 4 1.5 0,1 1 1 n limx-f = 0 a0 1 -3 0.5 -2 -1 1 2 3 4 Logarithmic function: f x log n a, Domain : x 0, Range : y lim logn a , limlogn a x 0 x Properties of Logarithmic functions: y log a x x a y 2.5 log a nm log a n log a m n log a log a n log a m m log a n m m log a n log n m log a m log a n limxf is + 2 1.5 gx = lnx 1 0.5 1 2 3 1, 0 -0.5 log10 n log n -1 log e n ln n -1.5 log n 1 0; ln e 1; log10 1 limx0 f = - -2 Note: log x is understood to be log10 x and ln x is log e x “e” is special base and e 2.718 4 5 6 7
