The given Trigonometric function is

y = Cos (x)

As the maximum value of Cosine (Theta) is 1. i.e

Maximum value of Cos (x) = 1

Cos (x) = cos (0 or 2 π)

If Cos (x) = Cos A

Then General formula for evaluating x is ,

x = 2 n π \pm A, for n =......-3,-2,-1,0,1,2,3,4,5.....

Here, A= 0, so the value of x is =2 n π \pm 0

x= 2 n π

dedylja [7]
She must at least score a 38
To get the average you need to add 45 + 32 + 37 together than divide it by the amount of numbers added, in this case 3. 

45 + 32 + 37 = 114
114÷3 = 38

This keeps on confusing me. Please explain it to me.
9966 [12]

Answer:

x=-10

Step-by-step explanation:

the picture is showing

1+1= -1 + -1 + -1 + -1 + -1 + -1 + -1 + -1 + -x

simplified its:

2= -8 + -x

I think that the answer is x=-10 cuz if u did -8 - -10 then the two negatives make a positive and it makes 2 but idk if the minus sign before the x means minus or negative so this might be the answer but dont blame me if im wrong. I warned you. If its right plz write that.
