31.21=40sin(25g)

Solution

31.21 = 40 sin (25 g)

Solution

g = \frac{0.89506 \dots}{25} + \frac{2 πn}{25}, g = \frac{π}{25} - \frac{0.89506 \dots}{25} + \frac{2 πn}{25}

Degrees

g = 2.05133 \dots^{\circ} + 14. 4^{\circ} n, g = 5.14866 \dots^{\circ} + 14. 4^{\circ} n

Solution steps

31.21 = 40 sin (25 g)

Switch sides

40 sin (25 g) = 31.21

Divide both sides by

40

40 sin (25 g) = 31.21

Divide both sides by

40

\frac{40 sin ( 25 g )}{40} = \frac{31.21}{40}

Simplify

sin (25 g) = 0.78025

sin (25 g) = 0.78025

Apply trig inverse properties

sin (25 g) = 0.78025

General solutions for

sin (25 g) = 0.78025

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π - arcsin (a) + 2 πn

25 g = arcsin (0.78025) + 2 πn, 25 g = π - arcsin (0.78025) + 2 πn

25 g = arcsin (0.78025) + 2 πn, 25 g = π - arcsin (0.78025) + 2 πn

Solve

25 g = arcsin (0.78025) + 2 πn : g = \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

25 g = arcsin (0.78025) + 2 πn

Divide both sides by

25

25 g = arcsin (0.78025) + 2 πn

Divide both sides by

25

\frac{25 g}{25} = \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

Simplify

g = \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

g = \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

Solve

25 g = π - arcsin (0.78025) + 2 πn : g = \frac{π}{25} - \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

25 g = π - arcsin (0.78025) + 2 πn

Divide both sides by

25

25 g = π - arcsin (0.78025) + 2 πn

Divide both sides by

25

\frac{25 g}{25} = \frac{π}{25} - \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

Simplify

g = \frac{π}{25} - \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

g = \frac{π}{25} - \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}

g = \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}, g = \frac{π}{25} - \frac{arcsin ( 0.78025 )}{25} + \frac{2 πn}{25}
