cos(8x)*8=0

cos (8 x) \cdot 8 = 0

x = \frac{π}{16} + \frac{πn}{4}, x = \frac{3 π}{16} + \frac{πn}{4}

Solution steps

cos (8 x) \cdot 8 = 0

Divide both sides by

8

cos (8 x) = 0

General solutions for

cos (8 x) = 0

8 x = \frac{π}{2} + 2 πn, 8 x = \frac{3 π}{2} + 2 πn

Solve

8 x = \frac{π}{2} + 2 πn : x = \frac{π}{16} + \frac{πn}{4}

Solve

8 x = \frac{3 π}{2} + 2 πn : x = \frac{3 π}{16} + \frac{πn}{4}

x = \frac{π}{16} + \frac{πn}{4}, x = \frac{3 π}{16} + \frac{πn}{4}

\frac{13}{12} = cosh (\frac{x}{120})

θ, r = - \frac{3}{r cos ( θ )}

sin^{2} (x) + sin (2 x) = 1

T, y = sin (2 T)

sin (4 7^{\circ}) = cos (x)
