cos(t)= 40/41

cos (t) = \frac{40}{41}

t = 0.22131 \dots + 2 πn, t = 2 π - 0.22131 \dots + 2 πn

Solution steps

cos (t) = \frac{40}{41}

Apply trig inverse properties

t = arccos (\frac{40}{41}) + 2 πn, t = 2 π - arccos (\frac{40}{41}) + 2 πn

Show solutions in decimal form

t = 0.22131 \dots + 2 πn, t = 2 π - 0.22131 \dots + 2 πn

5 tan (x) = 12

cos^{2} (a) + cos (a) = 0

5 tan (x) = - 5

- 2 cos (θ - 1) = 0.5

cos (θ) = \frac{1}{9}
