how do i simplify (secx  cosx) / sinx? i tried splitting the numerator up so that i had (secx / sinx)  (cosx / sinx) and then i changed sec x to 1/ cosx so that i had ((1/cosx)/ sinx)  (cos x / sinx) after that i get stuck

cos(3π/4+x) + sin (3π/4 x) = 0 = cos(3π/4)cosx + sin(3π/4)sinx + sin(3π/4)cosx  cos(3π/4)sinx = 1/sqrt2cosx + 1/sqrt2sinx + 1/sqrt2cosx  (1/sqrt2sinx) I canceled out 1/sqrt2cosx and 1/sqrt2cosx Now I have 1/sqrt sinx +

tanx+secx=2cosx (sinx/cosx)+ (1/cosx)=2cosx (sinx+1)/cosx =2cosx multiplying both sides by cosx sinx + 1 =2cos^2x sinx+1 = 2(1sin^2x) 2sin^2x + sinx1=0 (2sinx+1)(sinx1)=0 x=30 x=270 but if i plug 270 back into the original

1/tanxsecx+ 1/tanx+secx=2tanx so this is what I did: =tanx+secx+tanxsecx =(sinx/cosx)+ (1/cosx)+(sinx/cosx)(1/cosx) =sinx/cosx+ sinx /cosx= 2tanxI but I know this can't be correct because what I did doesn't end as a

How do I solve this? tan^2x= 2tanxsinx My work so far: tan^2x  2tanxsinx=0 tanx(tanx  2sinx)=0 Then the solutions are: TanX=0 and sinX/cosX = 2 sin X Divide through by sinX: we have to check this later to see if allowed (ie sinX
