cos(x)=0.1234

cos (x) = 0.1234

x = 1.44708 \dots + 2 πn, x = 2 π - 1.44708 \dots + 2 πn

Solution steps

cos (x) = 0.1234

Apply trig inverse properties

x = arccos (0.1234) + 2 πn, x = 2 π - arccos (0.1234) + 2 πn

Show solutions in decimal form

x = 1.44708 \dots + 2 πn, x = 2 π - 1.44708 \dots + 2 πn

tan (2 x) = + \frac{9}{40}

x, y = cos (6 x)

12 cos^{2} (x) - 6 sin (x) - 6 = 0 [360]

sin (θ) = - 0

tan (x) = \frac{15}{12}
