    Assignment:Find the solution set of inequality (1.8-4.4(t^2))^2+((3*t)-0.8*t^2+1.2)^2 <1 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( 1.8 - 4.4 * ( t ^ 2 ) ) ^ 2 + ( ( 3 * t ) - 0.8 * t ^ 2 + 1.2 ) ^ 2 <1         (1)

---

    From inequality(1)：
         -0.62756 < t < -0.435293

---

    The final solution set is :
         -0.62756 < t < -0.435293
