sin(2x)= 3/5

sin (2 x) = \frac{3}{5}

x = \frac{0.64350 \dots}{2} + πn, x = \frac{π}{2} - \frac{0.64350 \dots}{2} + πn

Solution steps

sin (2 x) = \frac{3}{5}

Apply trig inverse properties

2 x = arcsin (\frac{3}{5}) + 2 πn, 2 x = π - arcsin (\frac{3}{5}) + 2 πn

Solve

2 x = arcsin (\frac{3}{5}) + 2 πn : x = \frac{arcsin ( \frac{3}{5} )}{2} + πn

Solve

2 x = π - arcsin (\frac{3}{5}) + 2 πn : x = \frac{π}{2} - \frac{arcsin ( \frac{3}{5} )}{2} + πn

x = \frac{arcsin ( \frac{3}{5} )}{2} + πn, x = \frac{π}{2} - \frac{arcsin ( \frac{3}{5} )}{2} + πn

Show solutions in decimal form

x = \frac{0.64350 \dots}{2} + πn, x = \frac{π}{2} - \frac{0.64350 \dots}{2} + πn

- cos (x) = sin (x)

2 cos^{2} (x) + 5 cos (x) - 3 = 0

x, cos (x) = 1

cos (x) cot^{2} (x) = cos (x)

4 sin (x) cos (x) = - 9 cos (x)
