How do you sketch $theta=(7pi)/4$ in standard position?

1 Answer

Jul 29, 2015

$2pi = (8pi)/4$ is one full revolution
$rarr (7pi)/4$ is $pi/4$ less than a full revolution.

Explanation:

...to look at it another way:

$pi/2$ is a right angle

$(7pi)/4 = 3*(pi/2) + 1/2*pi/2$
$color(white)("XXXX")$ is 3 right-angles plus half a right angle
