Let P(t) be the point on the unit circle U that corresponds P(t) = (-8/17, 15/17).  Find the following


(a) P (t + pi) = (?,?)
(b) P (t-pi) = (?,?)
(c) P (-t) = (?,?)
(d) P (-t-pi) = (?,?)
~~~~~~~~~~~~



<pre>
(a)  P (t + pi) = (8/17,-15/17)     ( <<<---===  the opposite point on the unit circle).



(b)  P (t - pi) = (8/17,-15/17)     ( <<<---===  the same opposite point on the unit circle).



(c)  P (-t) = (-8/17,-15/17)        ( <<<---===  the mirror reflection of the given point about x-axis)



(d)  P (-t-pi) = (8/17,15/17)       ( <<<---===  the opposite point to that of (c) )

Solved. &nbsp;&nbsp;&nbsp;&nbsp;// &nbsp;&nbsp;&nbsp;&nbsp;All questions are answered.


Do you understand my English ?

It is my second case at this forum, &nbsp;when I respond to the post written in the language other than &nbsp;English.


My first case was with &nbsp;Hindi. &nbsp;&nbsp;Again, &nbsp;I &nbsp;used &nbsp;GOOGLE &nbsp;translation in that case . . .
