cos(x)= 15/17

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

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

Solution steps

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

Apply trig inverse properties

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

Show solutions in decimal form

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

6 cos (θ) - 3 = 0

3 cos (θ) + 3 = 2 sin^{2} (θ)

- 33 + 7 csc (\frac{θ}{5} + 2 3^{\circ}) = 53

10 sin (x) tan (x) + tan (x) = 0

2 sin^{2} (θ) + sin (θ) - 1 = 0, 0 \leq θ \leq 2 π
