cos(x)= 5/13

cos (x) = \frac{5}{13}

x = 1.17600 \dots + 2 πn, x = 2 π - 1.17600 \dots + 2 πn

Solution steps

cos (x) = \frac{5}{13}

Apply trig inverse properties

x = arccos (\frac{5}{13}) + 2 πn, x = 2 π - arccos (\frac{5}{13}) + 2 πn

Show solutions in decimal form

x = 1.17600 \dots + 2 πn, x = 2 π - 1.17600 \dots + 2 πn

3 sin (x) + cos (x) = 1

sin (t) = \frac{1}{2}

sin (θ) - cos (θ) = 2

sin (θ) + 3 cos (θ) = 0

cos (x) + 2 sin (x) cos (x) = 0
