cos(x)=-0.79497329

cos (x) = - 0.79497329

x = 2.48975 \dots + 2 πn, x = - 2.48975 \dots + 2 πn

Solution steps

cos (x) = - 0.79497329

Apply trig inverse properties

x = arccos (- 0.79497329) + 2 πn, x = - arccos (- 0.79497329) + 2 πn

Show solutions in decimal form

x = 2.48975 \dots + 2 πn, x = - 2.48975 \dots + 2 πn

sin (x) + sin (x) = 2

cos (θ) = \frac{1}{6}

sin (x) - 3 cos (x) = 2

(sin (x) - 1) (sin (x) - 3) = 0

x, sin (x) + y^{2} = 4
