cos(0.568x-2.595)=0

Solution

cos (0.568 x - 2.595) = 0

Solution

x = \frac{125 π}{142} + \frac{2595}{568} + \frac{250 πn}{71}, x = \frac{2595}{568} + \frac{375 π}{142} + \frac{250 πn}{71}

Degrees

x = 420.21575 \dots^{\circ} + 633.80281 \dots^{\circ} n, x = 737.11716 \dots^{\circ} + 633.80281 \dots^{\circ} n

Solution steps

cos (0.568 x - 2.595) = 0

0.568 x - 2.595 = \frac{π}{2} + 2 πn, 0.568 x - 2.595 = \frac{3 π}{2} + 2 πn

0.568 x - 2.595 = \frac{π}{2} + 2 πn, 0.568 x - 2.595 = \frac{3 π}{2} + 2 πn

Solve

0.568 x - 2.595 = \frac{π}{2} + 2 πn : x = \frac{125 π}{142} + \frac{2595}{568} + \frac{250 πn}{71}

0.568 x - 2.595 = \frac{π}{2} + 2 πn

Multiply both sides by

1000

0.568 x - 2.595 = \frac{π}{2} + 2 πn

To eliminate decimal points, multiply by 10 for every digit after the decimal pointThere are

3

digits to the right of the decimal point, therefore multiply by

1000

0.568 x \cdot 1000 - 2.595 \cdot 1000 = \frac{π}{2} \cdot 1000 + 2 πn \cdot 1000

Refine

568 x - 2595 = 500 π + 2000 πn

568 x - 2595 = 500 π + 2000 πn

Move

2595

to the right side

568 x - 2595 = 500 π + 2000 πn

Add

2595

to both sides

568 x - 2595 + 2595 = 500 π + 2000 πn + 2595

Simplify

568 x = 500 π + 2000 πn + 2595

568 x = 500 π + 2000 πn + 2595

Divide both sides by

568

568 x = 500 π + 2000 πn + 2595

Divide both sides by
