View the step-by-step solution to:

1)Is sin2x = 2sinx an identity? 2)Is sinx=2sinx*cosx an identity?

1)Is sin2x = 2sinx an identity?
2)Is sinx=2sinx*cosx an identity?
3)Rewrite 2sin 30 degrees*cos 30 degrees as a single trig function
4)If sinx=5/13 and x is in quadrant I, then:
sin2x=
cos2x=
tan2x=
5)Convert squareroot[3]x-y+3=0 to normal form of a line
6)Convert xcos210 degrees+ysin210 degrees-5 to rectangular form of a line
