Question

(-1/sinx)-(-sinx)

Answer 1

-csc(x) + sin(x) ?? is that what we are looking for?

Answer 2

sorry I should put the whole thing. csc(-x)-sin(-x)=-cosxcotx

Answer 3

i just put the part where I was stuck

Answer 4

I failed mind reading class :)

Answer 5

combine the fractions

Answer 6

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

Answer 7

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

Answer 8

=-(cosx)^2/sinx

Answer 9

-(cos x)(cot x) sory.

Answer 10

very good!

Answer 11

you have to multiply both side by (-1) at some point....its helpful

Answer 12

you guys go too fast.

Answer 13

-1/sinx -(-sinx) becomes -1/sinx + 1/sinx ?

Answer 14

-1/sinx+sin^x/sinx

Answer 15

i missed my exponent 2

Answer 16

wait what?

Answer 17

so we have (-1+(sinx)^2)/sinx

Answer 18

ok got that part so now what?

Answer 19

(cosx)^2+(sinx)^2=1 so (cosx)^2=1-(sinx)^2 so -(cosx)^2=-1+(sinx)^2

Answer 20

so it becomes cos^2x/sinx?

Answer 21

don't forget your negative sign

Answer 22

ok but how does that equal -cosxcotx?

Answer 23

oh never mind i see it

Answer 24

ok
