19." remember "sin theta=(1)/(2),vec pi" Be told that "3sin theta-4sin^(3)theta=1

If sin theta=1/2 then prove that 3sin theta-4sin^3 theta=1

4sin(pi/3+theta)sin(pi/3-theta)=

If 3 sin 2 theta=2 sin 3 theta and 0 lt theta lt pi then sin theta=

If 3sin2 theta=2sin3 theta and 0

Prove that 4 sin theta sin(pi/3 + theta) sin (pi/3-theta) = sin 3 theta

sin4 theta can be written as (a) 4sin theta(1-2sin^(2)theta)sqrt(1-sin^(2)theta)(b)2sin theta cos theta sin^(2)theta(c)4sin theta-6sin^(3)theta(d) None of the above
