cos(x)= 7/16

cos (x) = \frac{7}{16}

x = 1.11797 \dots + 2 πn, x = 2 π - 1.11797 \dots + 2 πn

Solution steps

cos (x) = \frac{7}{16}

Apply trig inverse properties

x = arccos (\frac{7}{16}) + 2 πn, x = 2 π - arccos (\frac{7}{16}) + 2 πn

Show solutions in decimal form

x = 1.11797 \dots + 2 πn, x = 2 π - 1.11797 \dots + 2 πn

3 = - 2 cos (θ)

4 sin (3 x) = 2

3 sin (4 x) = 23

7 cosh (x) - 3 sinh (x) = 11

2 sin^{2} (x) - 3 sin (x) = 1
