solvefor x,2cos(x)-sqrt(2)=0

solve for

x, 2 cos (x) - 2 = 0

x = \frac{π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

Solution steps

2 cos (x) - 2 = 0

Move

2

to the right side

2 cos (x) = 2

Divide both sides by

2

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

General solutions for

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

x = \frac{π}{4} + 2 πn, x = \frac{7 π}{4} + 2 πn

cos (θ) = - \frac{4}{3}

cos (x) = \frac{2.16}{3.42}

2 cos^{2} (θ) - 3 sin (θ) - 3 = 0

sinh (x) = \frac{5}{12}, cosh (x)

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