Solve the equation: {eq}(\sec t + \tan t)^2 = \frac{1 + \sin t}{1 - \sin t} {/eq}. Fundamental Trigonometric Identity The fundamental trigonometric identity establishes that the squared sum of the sine and cosine of an angle equals 1, {eq}\sin^2 x+\cos^2...
therefore, sin 90 degree equals to the fractional value of 1/ 1. sin 90° = 1 the most common trigonometric sine functions are sin 90 degree plus theta \(\begin{array}{l}\sin (90^{\circ}+\theta )=\cos \theta\end{array} \) sin 90 degree minus theta \(\begin{array}{l}\sin...

由于sec^2 Does是一个常数(它是二次函数在域内的任意点都存在),而tan^2 Eventually 是交替两个陪衬赛道域因此二次)。根据上述等式我们推出了 To finish the proof that; sin squared plus cosine squared equals to a constant. 因此,证明了sin方+cos方始终为常数。 经过这些解释和推理,我们已经更好地理解了...
If ()()f(x)=g(x) and h(x)=sin x then ()()f(h(x)) equals ( ) A. g(sin x) B. cos x
如序列:f(k)=cos(5pi/6+pi/12) 的周期是12 而不是12/5 这是为什么呢?注:pi 是圆周率对于正弦序列:f(k)=sin(BK)=sin(Bk+2mpi)=sin[B(k+m2pi/B)]=sin[B(k+m2pi/B)] m=0,1,2...为什么N=2pi/B必须是整数才是序列的周期呢?如果N=2pi/B不是整数了,序列的周期就是N=M2pi/B ...
