Question
Solve for the indicated variable (listed after the semicolon). Restrict all answers to the interval [0,2pi] or [0,360degrees]
1) 4sin(x)cos(x) = 1; x
2) cos^2(t)sin(t)-sin(t) = 0; t
4sin(x)cos(x) = 1
2(2sin(x)cos(x)) = 1
2(sin(2x)) = 1
sin(2x) = (1/2)
2x = 30 or 150
x = 15 or 75 : pi/12 or 5pi/12
-----------------------------
cos(t)^2sin(t) - sin(t) = 0
sin(t)(cos(t)^2 - 1) = 0
sin(t)(-1 + cos(t)^2) = 0
sin(t)(-(1 - cos(t)^2) = 0
-sin(t)sin(t)^2 = 0
-sin(t)^3 = 0
sin(t)^3 = 0
sin(t) = 0
t = 0, 180, or 360 : 0, pi, or 2pi
