sec(x)=3

sec (x) = 3

x = 1.23095 \dots + 2 πn, x = 2 π - 1.23095 \dots + 2 πn

Solution steps

sec (x) = 3

Apply trig inverse properties

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

Show solutions in decimal form

x = 1.23095 \dots + 2 πn, x = 2 π - 1.23095 \dots + 2 πn

- sin (x) = cos (x)

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

4 sin (θ) + 3 = 1

25 cot^{2} (θ) - 1 = 0

cos (a) = \frac{5}{13}
