4cos(x-1)=0

4 cos (x - 1) = 0

x = \frac{π}{2} + 2 πn + 1, x = \frac{3 π}{2} + 2 πn + 1

Degrees

x = 147.29577 \dots^{\circ} + 36 0^{\circ} n, x = 327.29577 \dots^{\circ} + 36 0^{\circ} n

Solution steps

4 cos (x - 1) = 0

Divide both sides by

4

4 cos (x - 1) = 0

Divide both sides by

4

\frac{4 cos ( x - 1 )}{4} = \frac{0}{4}

Simplify

cos (x - 1) = 0

cos (x - 1) = 0

x - 1 = \frac{π}{2} + 2 πn, x - 1 = \frac{3 π}{2} + 2 πn

x - 1 = \frac{π}{2} + 2 πn, x - 1 = \frac{3 π}{2} + 2 πn

Solve

x - 1 = \frac{π}{2} + 2 πn : x = \frac{π}{2} + 2 πn + 1

x - 1 = \frac{π}{2} + 2 πn

Move

1

to the right side

x - 1 = \frac{π}{2} + 2 πn

Add

1

to both sides

x - 1 + 1 = \frac{π}{2} + 2 πn + 1

Simplify

x = \frac{π}{2} + 2 πn + 1

x = \frac{π}{2} + 2 πn + 1

Solve

x - 1 = \frac{3 π}{2} + 2 πn : x = \frac{3 π}{2} + 2 πn + 1

x - 1 = \frac{3 π}{2} + 2 πn

Move

1

to the right side

x - 1 = \frac{3 π}{2} + 2 πn

Add

1

to both sides

x - 1 + 1 = \frac{3 π}{2} + 2 πn + 1

Simplify

x = \frac{3 π}{2} + 2 πn + 1

x = \frac{3 π}{2} + 2 πn + 1

x = \frac{π}{2} + 2 πn + 1, x = \frac{3 π}{2} + 2 πn + 1

cos (θ) = \frac{5}{7}, cos (\frac{θ}{2}), 0^{\circ} < θ < 9 0^{\circ}

sin (x) + 4 = cos (x) + 3

\frac{sin ( 17 0 ^{\circ} )}{8} = \frac{sin ( B )}{5}

tan (x) = 0.01096
