General solutions for

cos (a) = 0.998482

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

a = arccos (0.998482) + 2 πn, a = 2 π - arccos (0.998482) + 2 πn

a = arccos (0.998482) + 2 πn, a = 2 π - arccos (0.998482) + 2 πn

Show solutions in decimal form

a = 0.05510 \dots + 2 πn, a = 2 π - 0.05510 \dots + 2 πn

3 - 4 sin (θ) = 4 - 6 sin (θ)

\frac{cos ( x )}{sin ( x )} = - 0.00172

x, r^{3} = sin (x)

\frac{( 7 cos ( 2 x ) + 7 )}{2} = \frac{π}{2}

tan (x) = - 1.036
