Find cot 0, sec 0, and cos 0, where is the angle shown in the figure. Give exact values, not decimals approximations.

Cot 0 = undefined

Sec0 = cos0 = 1

Step-by-step explanation:

According to trig identity

Cot theta = 1/sin theta

Sec theta = 1/cos theta

Hence

Cot 0 = 1/tan0

Cot 0 = 1/0

Since a/0 is undefined, hence cot 0 will be undefined

Sec 0 = 1/cos 0

Sec0 = 1/1 = 1

Cos 0 = 1

if he has no friends he cant give them out to his friends

step-by-step explanation:

no friends = cant give anything out

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
