General solutions for

cos (x) = 0.98

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

x = arccos (0.98) + 2 πn, x = 2 π - arccos (0.98) + 2 πn

x = arccos (0.98) + 2 πn, x = 2 π - arccos (0.98) + 2 πn

Show solutions in decimal form

x = 0.20033 \dots + 2 πn, x = 2 π - 0.20033 \dots + 2 πn

tan (3 x + \frac{π}{2}) = - 1

15 = 60 sin (\frac{π}{15 [ 0 - d ]}) + 75

cos (θ) = \frac{2 5}{58}

tan (θ) = \frac{m ^{2} - m ^{1}}{1 + m ^{2} \cdot m ^{1}}, m^{2}

0 = - 1 - tan^{2} (θ) + 2 tan (θ)
