1 answer:
Answer: The Diagram of the refracted angle is attached below
answer : ∅ = cos^-1 ( w/d )
Step-by-step explanation:
The trigonometric expression for the refracted angle
with respect to ; Distance ( d ) and width ( w )
Cos ∅ = Adjacent / Hypotenuse ----- ( 1 )
where; adjacent = W . Hypotenuse = d
back to equation 1
Cos ∅ = w / d
∴ ∅ = cos^-1 ( w/d )

The first five terms of the sequence are -10, -33, -125, -493, -1965
Explanation:
The given expression is
And is the first term of the sequence.
We need to determine the first five terms of the sequence.
<u>Second term:</u>
Substituting n = 2 in the expression , we have,
Thus, the second term is -33
<u>Third term:</u>
Substituting n = 3 in the expression , we have,
Thus, the third term is -125
<u>Fourth term</u><u>:</u>
Substituting n = 4 in the expression , we have,
Thus, the fourth term is -493
<u>Fifth term</u>:
Substituting n = 5 in the expression , we have,
Thus, the fifth term is -1965
Hence, the first five terms of the sequence are -10, -33, -125, -493, -1965
