If r is positive nx[x]=17 , what is hevalucosx?( (A)1 (B)2.5 (C)3 (D)4.25 14. For any positive number, r] denotes the largest integer less than or equal to r. For example, [ 4. 2] = 4, and[3]=3.1f [x]x=36. and [ y] y 71 where y 0, then y equals()....
Prove cosh t greater than or equal to 1 for all t. Simplify: y = sin^4x cos4x Is there an identity analogous to sin (2 x) = 2 sin x cos x for the hyperbolic functions? Explain. Let z = arctan (x^2 + y^2), x = e^(u) sin v, y = e^(u) cos v. Find dz/du. NO...

2013年10月某日，某高校学生杨某与曹某某因口角发生纠纷，双方还拉扯了几下，但当即被周围的学生劝开。曹某某回到宿舍后，越想越气愤，就想上杨某宿舍讨个说法，其同宿舍的刘某某一听便陪同曹某某一起去了杨某宿舍。曹某某与杨某争执了几句后，刘某某抄起一张板凳就向杨某的头上砸去，还连砸两下，杨某...
What is twice differentiable function example? For examplef(x)=x2is twice-differentiable. Is a constant function twice differentiable? Yes. f′ and all higher derivatives are identically equal to zero. differentiable once but not twice? (ft. Oreo) ...
For example rounding to the nearest floating-point number corresponds to an error of less than or equal to .5 ulp. However, when analyzing the rounding error caused by various formulas, relative error is a better measure. A good illustration of this is the analysis in the section Theorem 9...
【预期】易知函数为偶函数,故其图线关于y轴轴对称;因为SinX∈(-1,1)x∈(-∞,0)∪(0,+∞),故随着x绝对值价值,函数上下得振幅会越来越小;每次函数与x轴交叉的地方,都是Π的整数倍,此时y=0;x趋近极小值时,在SinX也在趋近极小值,且根据泰勒级数展开式,二者比例为1,故图线过(0,1)点,整根图线不分...
