sec(x)=-3

sec (x) = - 3

x = 1.91063 \dots + 2 πn, x = - 1.91063 \dots + 2 πn

Solution steps

sec (x) = - 3

Apply trig inverse properties

x = arcsec (- 3) + 2 πn, x = - arcsec (- 3) + 2 πn

Show solutions in decimal form

x = 1.91063 \dots + 2 πn, x = - 1.91063 \dots + 2 πn

2 tan (x) csc (x) + 2 csc (x) + tan (x) + 1 = 0

csc (x) + cot (x) = 3, 0 \leq x \leq 2 π

(tan^{2} (x) - 4) (2 cos (x) + 1) = 0

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

sin (- 2 x) = \frac{1}{2}
