Solution steps

cos (2 x + 1) = \frac{1}{2}

General solutions for

cos (2 x + 1) = \frac{1}{2}

2 x + 1 = \frac{π}{3} + 2 πn, 2 x + 1 = \frac{5 π}{3} + 2 πn

Solve

2 x + 1 = \frac{π}{3} + 2 πn : x = πn - \frac{1}{2} + \frac{π}{6}

Solve

2 x + 1 = \frac{5 π}{3} + 2 πn : x = πn - \frac{1}{2} + \frac{5 π}{6}

x = πn - \frac{1}{2} + \frac{π}{6}, x = πn - \frac{1}{2} + \frac{5 π}{6}

2 ∣ sin (4 x) ∣ = 0

sin (α) = - \frac{3}{5}

sin(2x)=(2*(1*10^{12}))/((1*10^7)^2)

sin (2 x) = \frac{2 \cdot ( 1 \cdot 1 0 ^{12} )}{( 1 \cdot 1 0 ^{7} ) ^{2}}

1+sin(θ)=((sqrt(3)+2))/2

1 + sin (θ) = \frac{( 3 + 2 )}{2}

-cos(θ)=-cos(2θ)

- cos (θ) = - cos (2 θ)
