Find the 6 Trig funtions for 135 degree angle
I know that how to find the 6 trig funtions I would need to identify P(x,y) or P(cos t,sin t).
At 135 degrees this would land the point with a reference angle of 35 degrees in quadrant II. The origin is 1 unit.
What I need help on is how my teacher gets ( - sqrt(2)/2, sqrt (2)/2 ) for the P(cos t, sin t).
