sec(x)=-3.5

sec (x) = - 3.5

x = 1.86054 \dots + 2 πn, x = - 1.86054 \dots + 2 πn

Degrees

x = 106.60154 \dots^{\circ} + 36 0^{\circ} n, x = - 106.60154 \dots^{\circ} + 36 0^{\circ} n

Solution steps

sec (x) = - 3.5

Apply trig inverse properties

sec (x) = - 3.5

General solutions for

sec (x) = - 3.5

sec (x) = - a \Rightarrow x = arcsec (- a) + 2 πn, x = - arcsec (- a) + 2 πn

x = arcsec (- 3.5) + 2 πn, x = - arcsec (- 3.5) + 2 πn

x = arcsec (- 3.5) + 2 πn, x = - arcsec (- 3.5) + 2 πn

Show solutions in decimal form

x = 1.86054 \dots + 2 πn, x = - 1.86054 \dots + 2 πn

(sin (x) - 1) = cos (x)

2 sin^{2} (x) = cos (2 x)

cos (x) = 0.96

2 sin (3 x) + 3 = 0

4 cos^{2} (θ) sin (θ) + 2 cos^{2} (θ) = 0
