cos(x)=-0.07

cos (x) = - 0.07

x = 1.64085 \dots + 2 πn, x = - 1.64085 \dots + 2 πn

Solution steps

cos (x) = - 0.07

Apply trig inverse properties

x = arccos (- 0.07) + 2 πn, x = - arccos (- 0.07) + 2 πn

Show solutions in decimal form

x = 1.64085 \dots + 2 πn, x = - 1.64085 \dots + 2 πn

2 tan (θ) + 9 = 0

cos (x) = - 0.73

5 cos^{2} (x) - 3 cos (x) = 2

9 tan^{2} (x) - 27 = 0

cos (x) = - 0.45
