cos(x)= 5/12

cos (x) = \frac{5}{12}

x = 1.14102 \dots + 2 πn, x = 2 π - 1.14102 \dots + 2 πn

Solution steps

cos (x) = \frac{5}{12}

Apply trig inverse properties

x = arccos (\frac{5}{12}) + 2 πn, x = 2 π - arccos (\frac{5}{12}) + 2 πn

Show solutions in decimal form

x = 1.14102 \dots + 2 πn, x = 2 π - 1.14102 \dots + 2 πn

2 cos^{2} (x) + cos (x) - 10 = 0

a, 9 0^{\circ} = 18 0^{\circ} - 2 \cdot arccos (\frac{2 a}{c})

cos (x) = \frac{π}{4}

cot (x) = \frac{3}{7}, cos (x) > 0

4 tanh (x) - \frac{1}{cosh ( x )} = 1
