cos^3(x^2)-3>0

Solution

cos^{3} (x^{2}) - 3 > 0

Solution

False for all x \in R

Solution steps

cos^{3} (x^{2}) - 3 > 0

Move

3

to the right side

cos^{3} (x^{2}) - 3 > 0

Add

3

to both sides

cos^{3} (x^{2}) - 3 + 3 > 0 + 3

Simplify

cos^{3} (x^{2}) > 3

cos^{3} (x^{2}) > 3

sin(4x)>cos(2x)

sin (4 x) > cos (2 x)

cos (2 x) \geq \frac{1}{2}

1/(sin(2x))< 1/(sin(x))

\frac{1}{sin ( 2 x )} < \frac{1}{sin ( x )}

1 - 4 sin^{2} (x) > 0

tan(x)>=-sqrt(3)

tan (x) \geq - 3
