4sin(x)=2.54648

4 sin (x) = 2.54648

x = 0.69010 \dots + 2 πn, x = π - 0.69010 \dots + 2 πn

Solution steps

4 sin (x) = 2.54648

Divide both sides by

4

sin (x) = \frac{2.54648}{4}

Apply trig inverse properties

x = arcsin (\frac{2.54648}{4}) + 2 πn, x = π - arcsin (\frac{2.54648}{4}) + 2 πn

Show solutions in decimal form

x = 0.69010 \dots + 2 πn, x = π - 0.69010 \dots + 2 πn

y, \frac{3}{2} = sin (arcsin (0) + y)

2 \cdot cos^{2} (x) - cos (x) - 1 = 0

tan^{2} (x) - cot (x) = 0

5 sec^{3} (x) - 20 sec (x) = 0

3 cot^{2} (x) - 1 = 0, x
