Question

can anyone help me on a quotient problem for Calculus on derivatives?

Answer 1

whats the prob?

Answer 2

y=(cosx)/(1-sinx) can you show the steps because I know I messed up somewhere but I just can extract exactly where.

Answer 3

what have you tried?

Answer 4

u know the quotient rule?

Answer 5

\[[\frac{t}{b}]'=\frac{bt'-b't}{b^2}\]

Answer 6

Yeah I do know the quotient rule.

Answer 7

yes amistre, u definetly know this:)

Answer 8

;)

Answer 9

ok Dandy, apply it for ur prb

Answer 10

Hmmm remember when you solve trig problems in calculus you have to simplify them using trig identity like Pythagorean theorem and double angel formula etc before you can eve get the correct answer

Answer 11

Well right now I'm at (-sinx+sin^2x-cosx+cos^2x)/(-sinx)^2

Answer 12

and I tried simplifying witht he trig identities but I'm not sure if I am applying them accordingly

Answer 13

y'=(1-sinx)(-sinx)-(cosx)(-cosx)/(1-sinx)^2

Answer 14

ohhhhhhhhhhhhhhhhh I see what I did wrong

Answer 15

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

Answer 16

I did the derivative wrong for v, it should of been -cosx because 1 is a constant.

Answer 17

yes :)

Answer 18

okay I think i did another computation error. now I'm at the final stages and I have
(-sinx+1)/(1-sinx)^2
