student789: cscx/cotx+tanx=cosx
Hi Student789
co sec = 1/ sin
co t = 1/ tan
** The first letter of the most familiar ratio matches the 3'rd letter of the less used ratio,
Lets see,
1/sinx divided by 1/tanx + tanx = cosx
1/sinx multiplied by tanx + tanx = cosx
NOW, tanx =sinx/cosx
1/sinx times sinx/cosx + sinx/cosx = cosx
1/cosx + sinx/cosx = cosx
(1+sinx) / cosx = cosx
1+sinx = cos
2x
1+sinx = 1-sin
2x
sin
2x + sinx = 0
sinx(sinx + 1) = 0
sinx = 0 or sinx = -1
Can you finish it ?
