Solve arccos (2x)=0

Evaluate

arccos (2 x) = 0

Find the domain

More Steps

arccos (2 x) = 0, - \frac{1}{2} \leq x \leq \frac{1}{2}

Use the inverse trigonometric function

2 x = cos (0)

Calculate the trigonometric value

2 x = 1

Divide both sides

\frac{2 x}{2} = \frac{1}{2}

Divide the numbers

x = \frac{1}{2}

Check if the solution is in the defined range

x = \frac{1}{2}, - \frac{1}{2} \leq x \leq \frac{1}{2}

Solution

x = \frac{1}{2}

Alternative Form

x = 0.5
