sec(y)=12

sec (y) = 12

y = 1.48736 \dots + 2 πn, y = 2 π - 1.48736 \dots + 2 πn

Solution steps

sec (y) = 12

Apply trig inverse properties

y = arcsec (12) + 2 πn, y = 2 π - arcsec (12) + 2 πn

Show solutions in decimal form

y = 1.48736 \dots + 2 πn, y = 2 π - 1.48736 \dots + 2 πn

- sin (x) + 3 cos (x - \frac{π}{2}) = 1

cos (3 0^{\circ} + u) = 0.8177

cos (x - \frac{3 π}{2}) = \frac{1}{2}

1 - 3 cos (2 θ) = 0

x, sin (\frac{π}{x}) = y - 1
