    \[\frac{\sin^2(x)}{\cos^2(x)} - \frac{\sin(x)}{\cos(x)} = 0\] = what makes sin(x) = 0?

    what ever makes sin(x) 0 makes tan(x) = 0

    since there are no values in the answer that zero it out what value of x can make sin(x) = cos(x) because if sin(x) = cos(x) sin(x)/cos(x) = 1 and 1 - 1 = 0

    Hmm, o.k. I understand the input you guys are giving me. Would anyone b willing to solve it step by step with me though? That way I fully understand step by step?

    ok i am getting tanx=y there fore y^2-y=0 y(y-1)=0 either or y=0 y+1=0 y=0 y=1 but y=tanx s put in above tanx=0 tanx=1 x=tan^-1(0) x=tan^-1(1) x=0degree x= 45 degree now convert degree into radians yourself hint::1degree=pi/180 rad

    So 0 degree into radians= 0. 45 degree into radians= pi/4

    remember when sin(x) = 1 sin(x)^(2) = 1^(2) = 1
