cos(x)= 1/9

cos (x) = \frac{1}{9}

x = 1.45945 \dots + 2 πn, x = 2 π - 1.45945 \dots + 2 πn

Solution steps

cos (x) = \frac{1}{9}

Apply trig inverse properties

x = arccos (\frac{1}{9}) + 2 πn, x = 2 π - arccos (\frac{1}{9}) + 2 πn

Show solutions in decimal form

x = 1.45945 \dots + 2 πn, x = 2 π - 1.45945 \dots + 2 πn

sin (θ) + 0.069 = 0

tan (θ) = 1.3

tan (x) = 0.25

2 sec (x) sin (x) + 2 = 4 sin (x) + sec (x)

4 sin (x) cos (x) - 3 cos (x) = 0
