cos^2(x)= 3/2

cos^{2} (x) = \frac{3}{2}

No Solution for x \in R

Solution steps

cos^{2} (x) = \frac{3}{2}

Solve by substitution

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

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

No Solution

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

No Solution

2 sin^{2} (x) + cos^{2} (x) + cos (x) - 1 = 0

14 4^{2} = 43.2 7^{2} + 7 2^{2} - 2 \cdot 43.27 \cdot 72 \cdot cos (x)

sin (8 x + 48) = cos (- 4 x + 26)

3 cos (x) + sec (14 5^{\circ}) = 1

sec^{2} (x) + 3 tan^{2} (x) = 13
