Question 873513
Given that sinø=4/7 and &#960;/2<ø<&#960; find the values of the other 5 trigonometric functions of ø
{{{sin(phi)=4/7}}}
{{{cos(phi)=-sqrt(1-sin^2(phi))=-sqrt(1-(16/49))=-sqrt(33/49)=-sqrt(33)/7)}}}
{{{tan(phi)=sin(phi)/cos(phi)=-4/sqrt(33)}}}
{{{csc(phi)=7/4}}}
{{{sec(phi)=-7/sqrt(33)}}}
{{{cot(phi)=-sqrt(33)/4}}}
