sec(t)=3

sec (t) = 3

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

Solution steps

sec (t) = 3

Apply trig inverse properties

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

Show solutions in decimal form

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

tan (θ) = - \frac{12}{5}

x, sin (2 x) = sin (x)

- 3 cos (2 θ) + 7 cos (θ) - 10 = - 5

3 cos (2 θ) = - 9 cos (θ) - 6

5 sin (x) cos (x) + cos (x) = 0
