Given function FX = x & # 178; + (2-A) x-2a, the solution of inequality FX ≥ 0

Given function FX = x & # 178; + (2-A) x-2a, the solution of inequality FX ≥ 0




Using trigonometric function to solve inequality: SiN x > cos x


SiNx cosx > 0 root 2 (root 2 / 2sinx root 2 / 2cosx) = root 2Sin (x + π / 4) > 0 - π / 4 + 2K π



How to solve the inequality sin α > 0, cos α > 0


From sin α > 0, cos α > 0
We can see that α can only be a quadrant angle
That is: 2K π
