cos(30+u)=0.8177

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

u = 0.61339 \dots + 36 0^{\circ} n - 3 0^{\circ}, u = 36 0^{\circ} - 0.61339 \dots + 36 0^{\circ} n - 3 0^{\circ}

Solution steps

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

Apply trig inverse properties

3 0^{\circ} + u = arccos (0.8177) + 36 0^{\circ} n, 3 0^{\circ} + u = 36 0^{\circ} - arccos (0.8177) + 36 0^{\circ} n

Solve

3 0^{\circ} + u = arccos (0.8177) + 36 0^{\circ} n : u = arccos (0.8177) + 36 0^{\circ} n - 3 0^{\circ}

Solve

3 0^{\circ} + u = 36 0^{\circ} - arccos (0.8177) + 36 0^{\circ} n : u = 36 0^{\circ} - arccos (0.8177) + 36 0^{\circ} n - 3 0^{\circ}

u = arccos (0.8177) + 36 0^{\circ} n - 3 0^{\circ}, u = 36 0^{\circ} - arccos (0.8177) + 36 0^{\circ} n - 3 0^{\circ}

Show solutions in decimal form

u = 0.61339 \dots + 36 0^{\circ} n - 3 0^{\circ}, u = 36 0^{\circ} - 0.61339 \dots + 36 0^{\circ} n - 3 0^{\circ}

cos (x - \frac{3 π}{2}) = \frac{1}{2}

1 - 3 cos (2 θ) = 0

x, sin (\frac{π}{x}) = y - 1

cos (\frac{3 θ}{2}) = 0

270 = 69 - tan (4 5^{\circ} + (\frac{x}{2}))
