Solve arccos(3x)=0 - Socratic AI (ScanMath)

Evaluate

arccos (3 x) = 0

Find the domain

More Steps

arccos (3 x) = 0, - \frac{1}{3} \leq x \leq \frac{1}{3}

Use the inverse trigonometric function

3 x = cos (0)

Calculate the trigonometric value

3 x = 1

Divide both sides

\frac{3 x}{3} = \frac{1}{3}

Divide the numbers

x = \frac{1}{3}

Check if the solution is in the defined range

x = \frac{1}{3}, - \frac{1}{3} \leq x \leq \frac{1}{3}

Solution

x = \frac{1}{3}

Alternative Form

x = 0. \dot{3}

Arccos(3x)=0
