Answer 1

Are you allowed to use a graphic calculator?

Answer 2

hello???

Answer 3

yes sir

Answer 4

but i dont no how to used it

Answer 5

If you have a graphing calculator you can use that to graph the function. If not,
go to the graphing website (link given below) and type in the function as:
(sin(x))^3 - cos(x) + 1
It will graph the function.
Position the cursor at each of the points where it crosses the x axis and it will tell you the x,y coordinates. All the x values are where the function becomes zero and those are your solutions. You need to go only from 0 to 2pi.

There should be 5 x values where the function goes to zero. You got the first three. There is two more.

Answer 15

5.918 and 6.283

Answer 16

But they want the answers in the nearest hundredth and so you need to round off to two decimals: 0, 4.71, 5.71, 5.92 and 6.28

I have to go. Good luck.
