solve Sinx=Cos2x-1 for 0¡Üx<2¦Ð

cos2x(2cosx+1)=0 Solve for x.

cos2x-cosx+1=0 solve this

how do you solve: find cos2x if sinx is equal to 1/5

sin*sin=1.732*sinx*cos2x

solve for sinx=cos2x (between 0 and 2pi)

Solve Sinx=Cos2x-1 for all values between 0 and 2pi

cos2x-sinx=0. Factor and solve for sinx

How do i solve sinx/cosx(sinx+cosx/sinx×cosx)=secx? I know it's 1/cosx because it equals secx but...

Solve for: 1+cosx/sinx + sinx/1+cosx = 1 My teacher said no solution, but I don't know how he go...
