Question 1014679
.
if sin theta is 3/5, and theta is in the first quadrant , find the other trigonomteric functions.
------------------------------------------------


<pre>
{{{sin(theta)}}} = {{{3/5}}}.


Then {{{cos(theta)}}} = {{{sqrt(1 - sin^2(theta))}}} = {{{sqrt(1 - (3/5)^2)}}} = {{{sqrt(1 - (9/25))}}} = {{{sqrt((25-9)/25)}}} = {{{sqrt(16/25)}}} = {{{4/5}}}.


tan(theta) = {{{sin(theta)/cos(theta)}}} = {{{((3/5))/((4/5))}}} = {{{3/4}}}.
