Given cosθ=1/3, find sin(90-θ)

natta225 [31]

Cos θ=1/3
cos θ=sen (90-θ)
therfore:
sen (90-θ)=1/3

To chek
θ=arc cos 1/3=70.53º

sin (90-θ)=sin (90º-70.53º)=sin 19.47≈0.3333≈1/3

Answer:

The function will be: f(n) = 2n

Step-by-step explanation:

An arithmetic sequence is a sequence where the common difference between consecutive terms is same

The sequence according to given information is:

2,4,6...

Here

a_1 = 2

a_2 = 4

a_3 = 6

the common difference will be:

$d = a_2-a_1 = 4-2 = 2\\d = a_3-a_2 = 6-4 = 2$

The arithmetic sequence is given by:

$a_n = a_1+(n-1)d$

Putting the values

$a_n = 2+(n-1)(2)\\a_n = 2+2n-2\\a_n = 2n$

Hence,

The function will be: f(n) = 2n
