Question 1023331
.
find values of the trigonometric functions of the angle (in standard position) whose terminal side passes through the given point (8,2)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
r = {{{sqrt(x^2 + y^2)}}} = {{{sqrt(8^2 + 2^2)}}} = {{{sqrt(68)}}} = {{{2*sqrt(17)}}}.

sin(x) = {{{y/r}}} = {{{2/(2*sqrt(17))}}} = {{{1/sqrt(17)}}}.

cos(x) = {{{x/r}}} = {{{8/(2*sqrt(17))}}} = {{{4/sqrt(17)}}}.

Find yourself the remaining functions.
