cos(c)= 15/17

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

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

Solution steps

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

Apply trig inverse properties

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

Show solutions in decimal form

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

sin (θ) = 0.3907

2 cos (4 x) - 3 = 0

tan (x) = sec^{2} (x)

sin (x) = 0, 8

sin (x) tan (x) = - 2 - cot (x) sin (x)
