0.25*cos(x)=-0.249

0.25 \cdot cos (x) = - 0.249

x = 3.05212 \dots + 2 πn, x = - 3.05212 \dots + 2 πn

Solution steps

0.25 cos (x) = - 0.249

Multiply both sides by

1000

250 cos (x) = - 249

Divide both sides by

250

cos (x) = - \frac{249}{250}

Apply trig inverse properties

x = arccos (- \frac{249}{250}) + 2 πn, x = - arccos (- \frac{249}{250}) + 2 πn

x = 3.05212 \dots + 2 πn, x = - 3.05212 \dots + 2 πn

cos (x) sin (x) cos (x) = 1 - sin^{2} (x)

sin (θ) = 1 - (1 - (cos (θ) - 1)^{2})

5 cos (x) - 3 sin (x) = 4

14.79 m = (\frac{7.6 1 _{0}^{2} sin ( 2 θ _{0} )}{g})

2 cos (x) + 3 cos (x) - 2 = 0
