and use pythagorus to find the unknown side ( which turns out to be sqrt(7) )

What is sqrt? I haven't learned that...

tan(theta ) = -3 / sqrt(7) , note: tan isneagtive in the 4th quadrant

sqaure root lol

\[\sqrt{7} ?\] , you must know

Oh okay thank you lol I got confused

ow, sin(-theta) - -sin(theta ) because sin is an odd function so sin(- theta ) = 3/4
anonymous
  • anonymous
and cos(-theta) = cos(theta) , because cos is even , so cos(-theta) = sqrt(7) / 4
