2cos(x)+1=cos(x)

2 cos (x) + 1 = cos (x)

x = π + 2 πn

Solution steps

2 cos (x) + 1 = cos (x)

Solve by substitution

cos (x) = - 1

cos (x) = - 1 : x = π + 2 πn

Combine all the solutions

x = π + 2 πn

sin (\frac{( 60 )}{7}) = sin (\frac{( 81 )}{a})

sin^{2} (x) + cos^{2} (x) = cos (x)

sin (\frac{x}{3}) = - 0.85

2 cos (3 θ) = 2

tan (θ) = 2, 0 < θ < (\frac{π}{2}), sin (\frac{θ}{2})
