Examples:
3 x 2 = 6
7 x 2 = 14
Both are greater than 2 .
Counter examples:
1 x 2 = 2
-6 x 2 = -12
Not greater than 2 .
You can factor out a 3t first, resulting in:
Now, let's factor the equation in the middle using the quadratic equation. Plug in the values to the quadratic equation:
Simplify, you get your
x's:
To write the equation in simplified form, you just write it this way:
That's your answer ^
Answer:
320 i think
Step-by-step explanation:
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
