tan(3.87x)=-0.78

tan (3.87 x) = - 0.78

x = - \frac{0.66242 \dots}{3.87} + \frac{πn}{3.87}

Solution steps

tan (3.87 x) = - 0.78

Apply trig inverse properties

3.87 x = arctan (- 0.78) + πn

Solve

3.87 x = arctan (- 0.78) + πn : x = - \frac{arctan ( \frac{39}{50} )}{3.87} + \frac{πn}{3.87}

x = - \frac{arctan ( \frac{39}{50} )}{3.87} + \frac{πn}{3.87}

Show solutions in decimal form

x = - \frac{0.66242 \dots}{3.87} + \frac{πn}{3.87}

sin (2 x) = \frac{( 2 m - 4 )}{5}

34 sin (\frac{π}{6} (x - 43)) = 34

3 sin (3 x) = 2

2 sinh (2 x) - 6 cosh (x) = 0

- cos (x) = - 1
