4sec^2(x)-3=0

4 sec^{2} (x) - 3 = 0

No Solution for x \in R

Solution steps

4 sec^{2} (x) - 3 = 0

Solve by substitution

sec (x) = \frac{3}{2}, sec (x) = - \frac{3}{2}

sec (x) = \frac{3}{2} :

No Solution

sec (x) = - \frac{3}{2} :

No Solution

No Solution for x \in R

cos^{2} (x) = \frac{1}{4}, 0 \leq x \leq 2 π

sin (θ) = - \frac{4}{9}

- sin (y) = 0

0 = 2 + 4 sin (θ)

cos (x) = \frac{71}{81}
