8400=624sin((2pi)/(365)t)+8736

Solution

8400 = 624 sin (\frac{2 π}{365} t) + 8736

Solution

t = - \frac{365 \cdot 0.56861 \dots}{2 π} + 365 n, t = \frac{365}{2} + \frac{365 \cdot 0.56861 \dots}{2 π} + 365 n

Degrees

t = - 1892.56302 \dots^{\circ} + 20912.95952 \dots^{\circ} n, t = 12349.04278 \dots^{\circ} + 20912.95952 \dots^{\circ} n

Solution steps

8400 = 624 sin (\frac{2 π}{365} t) + 8736

Switch sides

624 sin (\frac{2 π}{365} t) + 8736 = 8400

Move

8736

to the right side

624 sin (\frac{2 π}{365} t) + 8736 = 8400

Subtract

8736

from both sides

624 sin (\frac{2 π}{365} t) + 8736 - 8736 = 8400 - 8736

Simplify

624 sin (\frac{2 π}{365} t) = - 336

624 sin (\frac{2 π}{365} t) = - 336

Divide both sides by

624

624 sin (\frac{2 π}{365} t) = - 336

Divide both sides by

624

\frac{624 sin ( \frac{2 π}{365} t )}{624} = \frac{- 336}{624}

Simplify

\frac{624 sin ( \frac{2 π}{365} t )}{624} = \frac{- 336}{624}

Simplify

\frac{624 sin ( \frac{2 π}{365} t )}{624} : sin (\frac{2 π}{365} t)

\frac{624 sin ( \frac{2 π}{365} t )}{624}

Divide the numbers:

\frac{624}{624} = 1

= sin (\frac{2 π}{365} t)

Simplify

\frac{- 336}{624} : - \frac{7}{13}

\frac{- 336}{624}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{336}{624}

Cancel the common factor:

Apply trig inverse properties

sin (\frac{2 π}{365} t) = - \frac{7}{13}

General solutions for

sin (\frac{2 π}{365} t) = - \frac{7}{13}

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

\frac{2 π}{365} t = arcsin (- \frac{7}{13}) + 2 πn, \frac{2 π}{365} t = π + arcsin (\frac{7}{13}) + 2 πn

\frac{2 π}{365} t = arcsin (- \frac{7}{13}) + 2 πn, \frac{2 π}{365} t = π + arcsin (\frac{7}{13}) + 2 πn

Solve

\frac{2 π}{365} t = arcsin (- \frac{7}{13}) + 2 πn : t = - \frac{365 arcsin ( \frac{7}{13} )}{2 π} + 365 n

\frac{2 π}{365} t = arcsin (- \frac{7}{13}) + 2 πn

Simplify

arcsin (- \frac{7}{13}) + 2 πn : - arcsin (\frac{7}{13}) + 2 πn

arcsin (- \frac{7}{13}) + 2 πn

Use the following property:

arcsin (- x) = - arcsin (x)

arcsin (- \frac{7}{13}) = - arcsin (\frac{7}{13})

= - arcsin (\frac{7}{13}) + 2 πn

\frac{2 π}{365} t = - arcsin (\frac{7}{13}) + 2 πn
