Allgemeine Lösung für

csc (A) = \frac{9.43}{5}

csc (x) = a \Rightarrow x = arccsc (a) + 2 πn, x = π - arccsc (a) + 2 πn

A = arccsc (\frac{9.43}{5}) + 2 πn, A = π - arccsc (\frac{9.43}{5}) + 2 πn

A = arccsc (\frac{9.43}{5}) + 2 πn, A = π - arccsc (\frac{9.43}{5}) + 2 πn

A = 0.55886 \dots + 2 πn, A = π - 0.55886 \dots + 2 πn

cos (x) cos (3 5^{\circ}) = 1 - sin (x) sin (3 5^{\circ})

4 sin^{2} (x) + 2 sin (x) = 2, 0 \leq x \leq 2 π

3 tan (\frac{1}{3} x) = 8

1.6 5^{2} = 0.6 5^{2} + 1.7 7^{2} - 2 (0.65) (1.77) cos (A)

so l v e f or x, cos (3 x + \frac{π}{4}) = \frac{1}{2}
