cos(x)= 9/41

cos (x) = \frac{9}{41}

x = 1.34948 \dots + 2 πn, x = 2 π - 1.34948 \dots + 2 πn

Solution steps

cos (x) = \frac{9}{41}

Apply trig inverse properties

x = arccos (\frac{9}{41}) + 2 πn, x = 2 π - arccos (\frac{9}{41}) + 2 πn

Show solutions in decimal form

x = 1.34948 \dots + 2 πn, x = 2 π - 1.34948 \dots + 2 πn

csc^{2} (x) + csc (x) - 1 = 1

\frac{a}{sin ( a )} = \frac{a}{sin ( B )}

cos (θ) = 1, 0^{\circ} \leq θ \leq 18 0^{\circ}

x, z = cos (2 x + y)

16 tan^{2} (x) - 1 = 0
