5+4cos(x)=0

5 + 4 cos (x) = 0

No Solution for x \in R

Solution steps

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
