cos(x)=-31/52019

cos (x) = - \frac{31}{52019}

x = 1.57139 \dots + 2 πn, x = - 1.57139 \dots + 2 πn

Solution steps

cos (x) = - \frac{31}{52019}

Apply trig inverse properties

x = arccos (- \frac{31}{52019}) + 2 πn, x = - arccos (- \frac{31}{52019}) + 2 πn

Show solutions in decimal form

x = 1.57139 \dots + 2 πn, x = - 1.57139 \dots + 2 πn

csc (\frac{x}{4}) = 2

4 cos (θ) = sec (θ)

sin (x) + 3 cos (x) = - 2

cot (θ) + 4 csc (θ) = 6

sin (x) 2 = - sin (x)
