cos(x)= 11/61

cos (x) = \frac{11}{61}

x = 1.38947 \dots + 2 πn, x = 2 π - 1.38947 \dots + 2 πn

Solution steps

cos (x) = \frac{11}{61}

Apply trig inverse properties

x = arccos (\frac{11}{61}) + 2 πn, x = 2 π - arccos (\frac{11}{61}) + 2 πn

Show solutions in decimal form

x = 1.38947 \dots + 2 πn, x = 2 π - 1.38947 \dots + 2 πn

- 1 = sec (x)

tan (x) = \frac{59}{36}

3 csc (θ) + 2 = 0, 0 \leq θ \leq 2 π

2 cos^{2} (x) - cos (x) = 3

4 cos (t) = 3
