Question

3. Dado tan 8 = 12/5 determinar el valor de las demás funciones
trigonométricas.

Answer 1

tan = 12/5

CO = 12

CA = 5

h = $\sqrt{12^{2}+5^{2} }$

     $\sqrt{144 + 25} \\\sqrt{169} \\13$

sen = CO/h = 12/13

cos = CA/h = 5/13

tan = CO/CA = 12/5

cot = CA/CO = 5/12

sec = h/CA = 13/5

csc = h/CO = 13/12
