cos(t)= 40/41

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

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

Degrees

t = 12.68038 \dots^{\circ} + 36 0^{\circ} n, t = 347.31961 \dots^{\circ} + 36 0^{\circ} n

Solution steps

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

Apply trig inverse properties

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

General solutions for

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

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

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

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
