cos(θ)=-(sqrt(3))/7

cos (θ) = - \frac{3}{7}

θ = 1.82082 \dots + 2 πn, θ = - 1.82082 \dots + 2 πn

Degrees

θ = 104.32582 \dots^{\circ} + 36 0^{\circ} n, θ = - 104.32582 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (θ) = - \frac{3}{7}

Apply trig inverse properties

cos (θ) = - \frac{3}{7}

General solutions for

cos (θ) = - \frac{3}{7}

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

θ = arccos (- \frac{3}{7}) + 2 πn, θ = - arccos (- \frac{3}{7}) + 2 πn

θ = arccos (- \frac{3}{7}) + 2 πn, θ = - arccos (- \frac{3}{7}) + 2 πn

Show solutions in decimal form

θ = 1.82082 \dots + 2 πn, θ = - 1.82082 \dots + 2 πn

\frac{1}{tan ( x )} + \frac{cos ^{2} ( x )}{sin ( x )} = 0

1 sin (2 5^{\circ}) = 1.506 sin (x)

\frac{1}{2} tan (2 θ) = tan (θ)

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

\frac{sin ( y )}{80} = \frac{sin ( 4 0 ^{\circ} )}{60}
