cos(x)= 60/61

cos (x) = \frac{60}{61}

x = 0.18131 \dots + 2 πn, x = 2 π - 0.18131 \dots + 2 πn

Degrees

x = 10.38885 \dots^{\circ} + 36 0^{\circ} n, x = 349.61114 \dots^{\circ} + 36 0^{\circ} n

Solution steps

cos (x) = \frac{60}{61}

Apply trig inverse properties

cos (x) = \frac{60}{61}

General solutions for

cos (x) = \frac{60}{61}

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

x = arccos (\frac{60}{61}) + 2 πn, x = 2 π - arccos (\frac{60}{61}) + 2 πn

x = arccos (\frac{60}{61}) + 2 πn, x = 2 π - arccos (\frac{60}{61}) + 2 πn

Show solutions in decimal form

x = 0.18131 \dots + 2 πn, x = 2 π - 0.18131 \dots + 2 πn

cot (θ) = \frac{3}{8}

cot (x) = 2

cos (θ) cot (θ) = - cos (θ)

cos (θ) = \frac{( - \frac{4}{5} )}{7 13}

tan (\frac{x}{2}) = - \frac{1}{3}
