$\tan \left( {{270}^{\circ }}+{{0}^{\circ }} \right)=\dfrac{-1}{0}$ , which is N.D. or undefined. Now, to check whether the value is $+\infty \text{ or }-\infty $ , we should use the graph of $y=\tan \left( x \right)\text{ at }x={{270}^{\c...
If the sine of an angle in a right triangle is 1/2 and the opposite side is 5, what is the hypotenuse? A. 5 B. 10 C. 15 D. 20 相关知识点: 试题来源: 解析 B。正弦定义为对边/斜边,已知正弦值为 1/2,对边为 5,所以斜边 = 对边÷正弦值 = 5÷(1/2) = 10。
What is the reference angle of 140 degrees?Angles in Standard Position:Since an angle is made up of two rays with their starting points at the same place, it can occupy a plane in many ways. When it is drawn in standard position it means that the origins of the rays are at the ...
What is the equation of the sine function with amplitude of 8, period of {eq}2\pi {/eq}, phase shift of {eq}\pi/2 {/eq}, and a vertical shift of 10? Characteristics of the Sine Function: The fundamental features that characterize the ...
This is the least used but simplest type of inverter. The output waveform of this inverter is a square wave. The home appliances and most of all equipment that works on AC, designed for thesine wave. It converts the straight DC signal to a phase-shifting AC signal. But the output is ...

What is the limit of f(x) equals 1 as x approaches pi ? Solve. lim x goes to 0 x^{-2} sin(x) Find the limit: lim as x goes to 0 of sinx/sin3x. Evaluate the limit as (x,y) approaches (0,0) of {3y^4 sin(x-y)}/{x^4+y^4}. Calculate the limit of sin(x) ...
While the quotidian(每日的,平凡的) challenges of human existence may seem mundane(单调的,平凡的) to some, these same challenges are what bind us together in a shared experience, and it is this commonality(共性,共同性) that cultivates empathy(共鸣,同情,同理心), which is the sine qua non...
