2 less than a number n is (n - 2 ) and 3 times this is 3(n - 2 ), thus

3(n - 2) ≥ 5n ( greater than or equal to 5 times n )

3n - 6 ≤ 5n ( subtract 3n from both sides )

- 6 ≥ 2n ( divide both sides by 2 )

- 3 ≥ n or n ≤ - 3

Since n is less than or equal to - 3 use bracket ]

n ∈ ( - ∞, - 3 ] ← solution set

Evaluate the integral. (remember to use absolute values where appropriate. Use c for the constant of integration.) 5 cot5(θ) sin

$I=5\int \frac{cos^{4}\theta }{sin\theta }\times cos\theta d\theta \\\\I=5\int \left ( 1-sin^{2}\theta \right )^{2}\times \frac{cos\theta }{sin\theta }d\theta \\put\ \sin\theta =t\\\\dt=cos\theta d\theta \\\\I=5\int\frac{t^{4}+1-2t^{2}}{t}dt\ \ \ \ \ \ \ \ \ \ \because (a-b)^2=a^2+b^2-2ab\\\\I=5\left ( \int t^{3}dt + \int \frac{1}{t} -2\int t \right )dt$
