Need some help with solving trig equations and giving all solutions... My professor is very smart, but completly stupid when it comes to teaching the material so I need some help... Please only people who know what they are doing... No BSing since this is for a grade.
2cos^2(x)-1=0
tan(x)sin(x)+sin(x)=0
2sin^2(x)-sin(x)=1
2cos^2(x)-1=0
tan(x)sin(x)+sin(x)=0
2sin^2(x)-sin(x)=1
