WebNov 15, 2014 · 2cos 2 Θ + cos(Θ) - 1 = 0 factor (2cos(Θ) - 1) (cos(Θ) +1 ) = 0. So. setting both factors to 0, we have (2cos(Θ) - 1) = 0 add 1 to both sides. 2cos(Θ) = 1 divide both sides by 2. And setiing the other factor to 0, we have. cos(Θ) +1 = 0 subtract 1 from both sides. cos(Θ) = -1 and this happens at 180 degrees on [0, 360] WebQuestion 13 (1 point) Solve the equation 1−csc2(Θ)=−3 on the interval [0,2π].
