Locate the point Pt cos t sin t on the unite circle Please s

Locate the point P(t)= (cos t, sin t) on the unite circle. Please show your work a) 1.3 b)-7.2

Solution

P(t) = ( cost , sint)

a) t = 1.3 rad

cos1.3 = 0.27 ; sin1.3 = 0.96

Point ( 0.27 ,0.96) in Ist quadrant

b) t = -7.2 rad

cos(-7.2) = 0.608

sin( -7.2) = - 0.794

Point ( 0.608, - 0.794)
