tan(2x)=+9/40

tan (2 x) = + \frac{9}{40}

x = \frac{0.22131 \dots}{2} + \frac{πn}{2}

Solution steps

tan (2 x) = \frac{9}{40}

Apply trig inverse properties

2 x = arctan (\frac{9}{40}) + πn

Solve

2 x = arctan (\frac{9}{40}) + πn : x = \frac{arctan ( \frac{9}{40} )}{2} + \frac{πn}{2}

x = \frac{arctan ( \frac{9}{40} )}{2} + \frac{πn}{2}

Show solutions in decimal form

x = \frac{0.22131 \dots}{2} + \frac{πn}{2}

x, y = cos (6 x)

12 cos^{2} (x) - 6 sin (x) - 6 = 0 [360]

sin (θ) = - 0

tan (x) = \frac{15}{12}

6 sin (θ) + 3 sin (θ) tan (θ) = 3 sin (θ)
