1st-the reason i keep change my name because some of my friends are using my computer by their own name to asked questions. we are having a hard time solving each trig problems
2nd- if sin theta=0.6 and 90 degree <theta < 180 degree, find the exact value of sin 2 theta.
a.-0.6
b.-0.96
c.0.96
d. .28

  • trig -

    sin theta=.6 >>> theta= arc sin .6=36.86or 90-36.86

    sin106=.96
