tan(2y)=1

tan (2 y) = 1

y = \frac{π}{8} + \frac{πn}{2}

Degrees

y = 22. 5^{\circ} + 9 0^{\circ} n

Solution steps

tan (2 y) = 1

General solutions for

tan (2 y) = 1

tan (x)

periodicity table with

πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

2 y = \frac{π}{4} + πn

2 y = \frac{π}{4} + πn

Solve

2 y = \frac{π}{4} + πn : y = \frac{π}{8} + \frac{πn}{2}

2 y = \frac{π}{4} + πn

Divide both sides by

2

2 y = \frac{π}{4} + πn

Divide both sides by

2

\frac{2 y}{2} = \frac{\frac{π}{4}}{2} + \frac{πn}{2}

Simplify

\frac{2 y}{2} = \frac{\frac{π}{4}}{2} + \frac{πn}{2}

Simplify

\frac{2 y}{2} : y

\frac{2 y}{2}

Divide the numbers:

\frac{2}{2} = 1

= y

Simplify

\frac{\frac{π}{4}}{2} + \frac{πn}{2} : \frac{π}{8} + \frac{πn}{2}

\frac{\frac{π}{4}}{2} + \frac{πn}{2}

\frac{\frac{π}{4}}{2} = \frac{π}{8}

\frac{\frac{π}{4}}{2}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{π}{4 \cdot 2}

Multiply the numbers:

4 \cdot 2 = 8

= \frac{π}{8}

= \frac{π}{8} + \frac{πn}{2}

y = \frac{π}{8} + \frac{πn}{2}

y = \frac{π}{8} + \frac{πn}{2}

y = \frac{π}{8} + \frac{πn}{2}

y = \frac{π}{8} + \frac{πn}{2}

(- 6 cos (x) + 2 sin (x))^{2} + 32 sin^{2} (x) = 48

tan (x) + 5 = \frac{15 - 3}{3}

5 cos^{2} (x) - cos (x) - sin^{2} (x) = 0

tan (x) csc (x) - 2 tan (x) = 3 csc (x) - 6

x, sin (x) = ln (y)
