Question

how do i simplify trig identities

Answer 1

sec(x)-cos(x)/tan(x)

Answer 2

write tan x as sin x/cos x

Answer 3

(sec(x)-cos(x))/(sin(x)/cos(x))

Answer 4

yes, now multiply cos x in numerator and denominator.

Answer 5

working.

Answer 6

(sec(x)cos(x)-cos^2(x))/sin(x)

Answer 7

sec x cos x = 1

Answer 8

and whats 1-cos^2x = .... ?

Answer 9

you may also write cos x as 1/sec x

Answer 10

@hartnn 0?

Answer 11

no, \(\sin^2x+cos^2x=1\)
so whats 1-cos^2 x= ?

Answer 12

sin^2x

Answer 13

yes.
so now what is
sin^2 x / sin x =?

Answer 14

(2sin(x))/(sin(x))

Answer 15

?

Answer 16

no

Answer 17

sin^2 x = sin x* sin x

Answer 18

sin^2 x / sin x =

Answer 19

working

Answer 20

oh so it would just be sin x

Answer 21

yes.

Answer 22

my bad i was thinking of bringing the exponent down, thanks for your time

Answer 23

welcome ^_^
