cos(x)= 1/3 ,(3pi)/2 <x<2pi

cos (x) = \frac{1}{3}, \frac{3 π}{2} < x < 2 π

x = 2 π - 1.23095 \dots

Degrees

x = 289.47122 \dots^{\circ}

Solution steps

cos (x) = \frac{1}{3}, \frac{3 π}{2} < x < 2 π

Apply trig inverse properties

cos (x) = \frac{1}{3}

General solutions for

cos (x) = \frac{1}{3}

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

x = arccos (\frac{1}{3}) + 2 πn, x = 2 π - arccos (\frac{1}{3}) + 2 πn

x = arccos (\frac{1}{3}) + 2 πn, x = 2 π - arccos (\frac{1}{3}) + 2 πn

Solutions for the range

\frac{3 π}{2} < x < 2 π

x = 2 π - arccos (\frac{1}{3})

Show solutions in decimal form

x = 2 π - 1.23095 \dots
