solvefor x,sin(x+60)=cos(y-37)

Solution

solve for

x, sin (x + 6 0^{\circ}) = cos (y - 3 7^{\circ})

Solution

x = - y + 36 0^{\circ} n + 6 7^{\circ}, x = y + 18 0^{\circ} + 36 0^{\circ} n - 18 7^{\circ}

Radians

x = - y + \frac{67 π}{180} + 2 πn, x = y + π - \frac{187 π}{180} + 2 πn

Solution steps

sin (x + 6 0^{\circ}) = cos (y - 3 7^{\circ})

Rewrite using trig identities

cos (y - \frac{37 π}{180})

Use the following identity:

cos (x) = sin (9 0^{\circ} - x)

sin (\frac{π}{2} - (y - \frac{37 π}{180}))

sin (x + \frac{π}{3}) = sin (\frac{π}{2} - (y - \frac{37 π}{180}))

Apply trig inverse properties

sin (x + \frac{π}{3}) = sin (\frac{π}{2} - (y - \frac{37 π}{180}))

sin (x) = sin (y) \Rightarrow x = y + 2 π n, x = π - y + 2 π n

x + \frac{π}{3} = \frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn, x + \frac{π}{3} = π - (\frac{π}{2} - (y - \frac{37 π}{180})) + 2 πn

x + \frac{π}{3} = \frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn, x + \frac{π}{3} = π - (\frac{π}{2} - (y - \frac{37 π}{180})) + 2 πn

x + 6 0^{\circ} = 9 0^{\circ} - (y - 3 7^{\circ}) + 36 0^{\circ} n : x = - y + 36 0^{\circ} n + 6 7^{\circ}

x + \frac{π}{3} = \frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn

Move

6 0^{\circ}

to the right side

x + \frac{π}{3} = \frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn

Subtract

6 0^{\circ}

from both sides

x + \frac{π}{3} - \frac{π}{3} = \frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn - \frac{π}{3}

Simplify

x + \frac{π}{3} - \frac{π}{3} = \frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn - \frac{π}{3}

Simplify

x + 6 0^{\circ} - 6 0^{\circ} : x

x + 6 0^{\circ} - 6 0^{\circ}

Add similar elements:

6 0^{\circ} - 6 0^{\circ} = 0

= x

Simplify

9 0^{\circ} - (y - 3 7^{\circ}) + 36 0^{\circ} n - 6 0^{\circ} : - y + 36 0^{\circ} n + 6 7^{\circ}

\frac{π}{2} - (y - \frac{37 π}{180}) + 2 πn - \frac{π}{3}
