sin(2x)=5cos(2x)

sin (2 x) = 5 cos (2 x)

x = \frac{1.37340 \dots}{2} + \frac{πn}{2}

Solution steps

sin (2 x) = 5 cos (2 x)

Rewrite using trig identities

tan (2 x) = 5

Apply trig inverse properties

2 x = arctan (5) + πn

Solve

2 x = arctan (5) + πn : x = \frac{arctan ( 5 )}{2} + \frac{πn}{2}

x = \frac{arctan ( 5 )}{2} + \frac{πn}{2}

Show solutions in decimal form

x = \frac{1.37340 \dots}{2} + \frac{πn}{2}

5 sec (2 x) + 2 = 0

2.1 sin (θ) = 1.33 sin (θ + 9 0^{\circ})

1 sin (4 5^{\circ}) = 1.33 sin (θ)

3 cot^{2} (x) = 9

1 2^{(2)} = 1 3^{(2)} + 5^{(2)} - 2 (13) (5) cos (B)
