0=5+4cos(x)

0 = 5 + 4 cos (x)

No Solution for x \in R

Solution steps

0 = 5 + 4 cos (x)

Switch sides

5 + 4 cos (x) = 0

Move

5

to the right side

5 + 4 cos (x) = 0

Subtract

5

from both sides

5 + 4 cos (x) - 5 = 0 - 5

Simplify

4 cos (x) = - 5

4 cos (x) = - 5

Divide both sides by

4

4 cos (x) = - 5

Divide both sides by

4

\frac{4 cos ( x )}{4} = \frac{- 5}{4}

Simplify

cos (x) = - \frac{5}{4}

cos (x) = - \frac{5}{4}

- 1 \leq cos (x) \leq 1

No Solution for x \in R

35708 = 35795 cos (x)

sin (θ) = \frac{2 - 3}{10}

sin (x) = 0.844

2 cos (x) = - cos (x)

tan (x) = - 10
