Step-by-step explanation:
cot x + 2 tan x + tan³ x
Write in terms of sine and cosine:
(cos x / sin x) + 2 (sin x / cos x) + (sin³ x / cos³ x)
Find the common denominator:
(cos⁴ x / (sin x cos³ x) + 2 (sin² x cos² x / (sin x cos³ x)) + (sin⁴ x / (sin x cos³ x))
Add:
(cos⁴ x + 2 sin² x cos² x + sin⁴ x) / (sin x cos³ x)
Factor:
(sin² x + cos² x)² / (sin x cos³ x)
Pythagorean identity:
1 / (sin x cos³ x)
Multiply top and bottom by cos x:
cos x / (sin x cos⁴ x)
Simplify:
cot x sec⁴ x

Y=-2x+200 hope this helps
<span> For this case we have the following number:
710200
We are going to decompose this number as the sum of three numbers:
</span>

<span> Let's now write each number:
70000: seven hundred thousand
10000: ten thousand
200: two hundred
Therefore, the complete expression is:
Seven hundred ten thousand two hundred
Answer: Seven hundred ten thousand two hundred</span>
