3arccos(x)=pi

Solution

3 arccos (x) = π

Solution

x = \frac{1}{2}

Solution steps

3 arccos (x) = π

Divide both sides by

3

arccos (x) = \frac{π}{3}

Apply trig inverse properties

x = \frac{1}{2}

Popular Examples

3sin(2x)-2sin(2x)=0

3 sin (2 x) - 2 sin (2 x) = 0

2 cos (4 x) + 5 = 6

cos(2θ)=-(sqrt(3))/2 ,0<= θ<= 2pi

cos (2 θ) = - \frac{3}{2}, 0 \leq θ \leq 2 π

2cos^2(a)=1+cos(120)

2 cos^{2} (a) = 1 + cos (12 0^{\circ})

cos(x)=(11)/(sqrt(17*38))

cos (x) = \frac{11}{17 \cdot 38}
