ed hardy uk, combined with the vector and Sine, Cosine corners to achieve the transformation to solve the equation list. Questions four: boundedness of trigonometric functions with test values of trigonometric functions and vector operations most. Example 4] (2007 entrance Shaanxi volume), (z) = port b,
knock off oakleys, where the vector population (, cos2x), (1 + sin2x, 1),
vibram five fingers outlet, z ∈ R, and the function of a plant (-z) images After a point (hand, 2), (I) the number of realistic value of m; (Ⅱ) demand function, () and then the value of the minimum set of answers] (I), (z) a a · b a (1 + sin2x) + COs2xl valve l have known - Factory (curse) a m (1 + sin No.) + c. s number = l2: 1 + sin2x4-cos22r = 14-I (Ⅱ) by the (I) was _ Factory (z) = + fsin (zz + number), 1. *. When sin (2z + curse): 1, the plant (z) is the minimum l 1 a, j by the sin (2z + {) = 1, z values were set to l a police boat z). 1 Comment 1 involves trigonometric functions and vector computing the value of the most asked questions when I can be the first product based on the number of vector algorithms find the corresponding function of the basic relationship I, and then use the basic trigonometric formulas will be derived from algebraic l into a shape like a Asin (a ~ x + p) 4 -, l-type offerings Yu Hui vector stitch | Example 5] (2. O7 college entrance examination in Hubei volume) to 2. (Temple + curse) of the image by the vector n (~ hand, a 2) translation, the translation after the 0A · 2c. s (curse + curse) a Nang B. y = 2c. s (special - No.) + z capsule c. -Zcos (No. ~) a zD. = 2c. s (a x3, l: rz ,4-2 analysis of type 3 'a 2cos (specifically + curse + stupid) a 2-2c. s32 ten kinds of questions six {coordinates operations with vectors, test stick with the triangle inequality Lu beauty questions | lII one snapped I. ~ j one case of 6] (2006 entrance Hubei volume) based vector qr Ao coffee 23Il1) {: nx, co; sx) function, b the number = (, cosx a, c most osx large) values, x and E the R, ~ is a small period of weeks f (x;); l collection.

As an integer, make Idl minimum, only k-1, then d = (One, a 2) is asked for 2. Solution: (I) if the port b, then sin0 ten cos0, which was tan0 eleven 1 (One <head <number), so the 0-One; (11) South A a (sin0.1), b = (1. cos0)} n + bI-v / (sin0 +1) + (1 + cos0) a ~ / -3 + - 2 - (s-in-0 + - co-s0-); √ 3 +2 in (+ curse), when sin (+}) a 1:00, ln + bf get maximum value, that is, when one o'clock, Ia ~ bl maximum value of +1.
