cos(t)= 15/17

cos (t) = \frac{15}{17}

t = 0.48995 \dots + 2 πn, t = 2 π - 0.48995 \dots + 2 πn

Solution steps

cos (t) = \frac{15}{17}

Apply trig inverse properties

t = arccos (\frac{15}{17}) + 2 πn, t = 2 π - arccos (\frac{15}{17}) + 2 πn

Show solutions in decimal form

t = 0.48995 \dots + 2 πn, t = 2 π - 0.48995 \dots + 2 πn

cos (x) = - \frac{3}{2 3}

sec^{2} (x) - 6 sec (x) = 16

cos^{2} (θ) + sin^{2} (θ) = 4

6 arccos (x) - 3 π = 3 arccos (x)

3 sin (2 x) = sin (x)
