= -(1-(sin x)^2)/ sin x = -(cos x)^2/sin x = -(cos x)

-1/sinx+sinx*(sinx/sinx)

=-(cosx)^2/sinx

-1/sinx -(-sinx) becomes -1/sinx + 1/sinx ?
myininaya
  • myininaya
-1/sinx+sin^x/sinx

i missed my exponent 2
LaddiusMaximus
  • LaddiusMaximus
wait what?
myininaya
  • myininaya
so we have (-1+(sinx)^2)/sinx
LaddiusMaximus
  • LaddiusMaximus
ok got that part so now what?
myininaya
  • myininaya
(cosx)^2+(sinx)^2=1 so (cosx)^2=1-(sinx)^2 so -(cosx)^2=-1+(sinx)^2
LaddiusMaximus
  • LaddiusMaximus
so it becomes cos^2x/sinx?
myininaya
  • myininaya
don't forget your negative sign
LaddiusMaximus
  • LaddiusMaximus
ok but how does that equal -cosxcotx?
LaddiusMaximus
  • LaddiusMaximus
oh never mind i see it
myininaya
  • myininaya
ok
