cos(x)= 1/15

cos (x) = \frac{1}{15}

x = 1.50408 \dots + 2 πn, x = 2 π - 1.50408 \dots + 2 πn

Solution steps

cos (x) = \frac{1}{15}

Apply trig inverse properties

x = arccos (\frac{1}{15}) + 2 πn, x = 2 π - arccos (\frac{1}{15}) + 2 πn

Show solutions in decimal form

x = 1.50408 \dots + 2 πn, x = 2 π - 1.50408 \dots + 2 πn

cot (θ) = - 3, 0 \leq θ < 2 π

\frac{sin ( 9 0 ^{\circ} )}{458.912} = \frac{sin ( x )}{450}

0 = \frac{2 π ^{2} cos ( \frac{π x}{10} )}{25}

300 cos (7 0^{\circ}) = 375 cos (θ)

812.25 = 399.6001 + 400 - 1140 cos (a)
