[ 1/1Inequality]
    Assignment:Find the solution set of inequality 0.99     Question type: Inequality
    Solution:
    The inequality can be reduced to 2 inequalities：
        0.99 < sin x ^ 2 + cos x ^ 2         (1)
         sin x ^ 2 + cos x ^ 2 <1.01         (2)

---

    From inequality(1)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
    From inequality(2)：
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!

---

    From inequalities (1) and (2)
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!    (3)

---

    The final solution set is :
         x ∈ R (R is all real numbers),that is, in the real number range, the inequality is always established!
