arccos(2x)=pi

Solution

arccos (2 x) = π

Solution

x = - \frac{1}{2}

Solution steps

arccos (2 x) = π

Apply trig inverse properties

2 x = - 1

Solve

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

x = - \frac{1}{2}

Popular Examples

(cosh(0.2m))/(cosh(0.4m))=0.6

\frac{cosh ( 0.2 m )}{cosh ( 0.4 m )} = 0.6

solvefor t,x=4sin(t)solve for

t, x = 4 sin (t)

sin(2x)+1.5cos(x)=0

sin (2 x) + 1.5 cos (x) = 0

sin (w π) = 0

(1+cos(x))(1-sin(x))-cos^2(x)=0

(1 + cos (x)) (1 - sin (x)) - cos^{2} (x) = 0
