sec(x)=-5/2

sec (x) = - \frac{5}{2}

x = 1.98231 \dots + 2 πn, x = - 1.98231 \dots + 2 πn

Solution steps

sec (x) = - \frac{5}{2}

Apply trig inverse properties

x = arcsec (- \frac{5}{2}) + 2 πn, x = - arcsec (- \frac{5}{2}) + 2 πn

Show solutions in decimal form

x = 1.98231 \dots + 2 πn, x = - 1.98231 \dots + 2 πn

sin (4 θ) = 0

csc^{2} (θ) - 2 = 0

2 sin^{2} (x) + 11 cos (x) = 7

sin (A) = \frac{5}{13}

2 cos (x) = - 2
