Cosa = 8/17

Type your math problem... cosa = 8/17

Question

cos (a) = \frac{8}{17}

Solve the equation

a = {- arccos (\frac{8}{17}) + 2 kπ arccos (\frac{8}{17}) + 2 kπ, k \in Z

Alternative Form

a \approx {- 61.92751 3^{\circ} + 36 0^{\circ} k 61.92751 3^{\circ} + 36 0^{\circ} k, k \in Z

Alternative Form

a \approx {- 1.080839 + 2 kπ 1.080839 + 2 kπ, k \in Z
