solve the following trigonometric equation sin^2(x)-sin(x)=0. Give your answers in exact radians where 0<=x<2pi
Solution
sin^2(x)-sin(x)=0. Give your answers in exact radians where 0<=x<2pi
sinx( sinx -1) =0
sinx =0 -----> x = 0, pi
sinx-1 =0
x= sin^-1(1) = pi/4 , pi-pi/4 = pi/4 , 3pi/4
Solution : x = 0, pi/4 , 3pi/4 , pi
