tan(2x)=2

tan (2 x) = 2

x = \frac{1.10714 \dots}{2} + \frac{πn}{2}

Solution steps

tan (2 x) = 2

Apply trig inverse properties

2 x = arctan (2) + πn

Solve

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

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

Show solutions in decimal form

x = \frac{1.10714 \dots}{2} + \frac{πn}{2}

sin (2 x) = cos (2 x) + 1

8 sin^{2} (x) - 2 = 0

y, sin (x) = x (1 + tan (y))

sin (2 x) - sin (x) = 0, (0, 2 π)

sin^{4} (x) + cos^{4} (x) = \frac{7}{9}
