Your getting that error because your compiling a function that does not have x or y defined. Its a normal error that occurs when the function is compiled. Just try calling the function from the command window and make sure to input variables for x and y ( i.e...
结果1 题目【题目】三角函数:sin(arctan x)=?cos(arctan x)=?why? 相关知识点: 试题来源: 解析 【解析】令arctan x=θ 所以 tanθ=x 且0在-90°到正 90°之间!因为 tanθ=x 所以sin0=±x/V(x2+1) cos= ±1/V(x2+1) 反馈 收藏 ...
Why does sin x diverge? Divergent In mathematics, a divergent series is an infinite series that is not convergent, meaning that the infinite sequence of the partial sums of the series does not have a finite limit. If a series converges, the individual terms of the series must approach zero...

Where does cos(x) equal 1/4? Where does cos(x) equal 1/2? Rewrite cos (x - 11pi/6) in terms of sin(x) and cos(x). What is cos(x) times cos(x) simplified? Prove the identity. cos(x-y)/cos x cos y=1+tan xtan y ...
Our work has several limitations. Despite the large total number of faces, some populations may be undersampled once we omitted individuals for whom data on body height was lacking. However, this does not affect the reported patterns of SShD. Future research would benefit from including an even...
Does cot have vertical asymptotes? The vertical asymptotes for y=cot(x) y = cot ( x ) occur at 0 , π , and every πn , where n is an integer. Does sin and cos have asymptotes? It will have zeros where the sine function has zeros, and vertical asymptotes where the cosine functio...
Explain why the functior f(x)=cos\ x, for -(π )2≤q x≤q (π )2, has no inverse. 相关知识点: 试题来源: 解析 On this interval, the function is not one-to-one since, for example cos (- (π )4)=cos ( (π )4) but - (π )4≠q (π )4....
