cos(x)=(4.6)/(8.6)

cos (x) = \frac{4.6}{8.6}

x = 1.00642 \dots + 2 πn, x = 2 π - 1.00642 \dots + 2 πn

Solution steps

cos (x) = \frac{4.6}{8.6}

Apply trig inverse properties

x = arccos (\frac{4.6}{8.6}) + 2 πn, x = 2 π - arccos (\frac{4.6}{8.6}) + 2 πn

Show solutions in decimal form

x = 1.00642 \dots + 2 πn, x = 2 π - 1.00642 \dots + 2 πn

5 tan (x) + 5 tan^{2} (x) = 0

t, x = r cos (t)

0 = 2 sin (θ) + 3

8 sec^{2} (x) - 8 sec (x) = 16

50 = 36 sin (\frac{2 π}{365} (t - 101)) + 14
