2-cos(2x)+1=0

2 - cos (2 x) + 1 = 0

No Solution for x \in R

Solution steps

2 - cos (2 x) + 1 = 0

Group like terms

- cos (2 x) + 2 + 1 = 0

Add the numbers:

2 + 1 = 3

- cos (2 x) + 3 = 0

Move

3

to the right side

- cos (2 x) + 3 = 0

Subtract

3

from both sides

- cos (2 x) + 3 - 3 = 0 - 3

Simplify

- cos (2 x) = - 3

- cos (2 x) = - 3

Divide both sides by

- 1

- cos (2 x) = - 3

Divide both sides by

- 1

\frac{- cos ( 2 x )}{- 1} = \frac{- 3}{- 1}

Simplify

cos (2 x) = 3

cos (2 x) = 3

- 1 \leq cos (x) \leq 1

No Solution for x \in R

cos (2 x) = \frac{3}{4}

sin (x) = 0.7, 0^{\circ} \leq x \leq 36 0^{\circ}

- 2 + cot (θ) = - 3, 0 \leq θ < 2 π

sec (θ) csc (θ) = 2 csc (θ)

sin (A) = \frac{( 60 ) sin ( 15 5 ^{\circ} )}{97.73}
