Jun 23, 2024 · Basically, the behavior of 1+sec (x) is different in each range. You found where 1+sec (x) and y=3 intersect, but you still need to make sure the bounded region is meaningful. …

Dec 17, 2018 · need help with arcsin (sin) problem. So I have the problem arcsin (sin (5pi/3)) Since it's in quadrant four I did the formula 2pi-theta (5pi/3) and got pi/3. But it keeps saying …

Feb 14, 2020 · Why is the answer to this not also (5pi)/6, since inverse operations cancel. I see that pi/6 is also true, but the instructions dont mention finding analogous point.

(e i (1.5pi))i = e i2 1.5pi = e -1.5pi = 0.0089... The end result computes differently. I feel sure that I've made some obvious stupid blunder, but I'm failing to see where. Nonetheless, the 'wrong' …

sinx是第一个被求反函数的。当时sin cos tan cot接到通知来讨论三角函数的周期性问题，sinx刚到初等函数大厅，门口的守卫把sinx身边的常数拦了下来，sinx感觉到事情不太对劲，但停顿一 …

May 16, 2024 · So sin (theta) = 1/2 at two points. pi/6 and 5pi/6 (it may be easier to draw or use a unit circle to see this) However, if you complete 'laps' around the circle you can go back over …

Jun 30, 2014 · My problem I'm trying to solve reads "Which number is the largest?" and gives trig values such as tan pi/6, tan pi/4, tan 5pi/6. This is a practice exam that has answers and the …

Jul 13, 2017 · If the answer is 5pi/6 then x would be 5pi/3, which is outside the domain. 5pi/6 is the value of x so the correct answer is C. What book is this from?

Feb 25, 2022 · You are misreading the annotation. It says that the distances from 0 to pi/6 and from 5pi/6 to pi are both pi/6.

May 17, 2020 · Calculator is wrong So my calculator (texas instruments) says that cos (3.5pi) is 3 * 10 -13 when it of course should be 0. When I use 0.5pi it works. It also works for 1.5pi and …
