Question

did i simplify this right???
cos^2(theta)(1+tan^2(theta))
simplified
1 or (cos^2(theta)) (1/cos^2(theta))

Answer 1

yes, u r right... the answer is 1

Answer 2

thanks you :)

Answer 3

yw

Answer 4

can you help me with another problem???

Answer 5

sure

Answer 6

okay the given function is : \[\cot(x)\div(\csc(-x))\] i have it simplified down to\[\cos(x)(-\sin(x))divsin(x)\] and now i am stuck

Answer 7

ok, convert cot(x) to cos(x)/sin(x)
and the identity of csc(-x) = -csc(x) and dont forget csc(x) = 1/sin(x)
so, cot(x) : csc(-x) = cot(x) : (-csc(x)
= cos(x)/sin(x) : 1/(-sin(x)
= cos(x)/sin(x) * -sin(x)/1
= -cos(x)

Answer 8

ty

Answer 9

welcome

Answer 10

i wasnt sure if you could do that since the one sin was negative and the other was not

Answer 11

nopes...

Answer 12

nope as in my thinking is wronog???

Answer 13

opsss. sory i was misscomunication :)

Answer 14

so is -cos(x) the answer?

Answer 15

yes it is

Answer 16

any else

Answer 17

yea (cos(x))/sec(x)+tan(x) --> cos^2(x)/sin(x)
correct? -->=simplifies to

Answer 18

is ur question

Answer 19

did i simplify it correctly?

Answer 20

cos(x)/(sec(x)+tan(x)) OR
cos(x)/sec(x) + tan(x)

Answer 21

which one :
