Question

TRIG ID's
cot x =1/tan OR cot x = cos x/sin x

Answer 1

both?

Answer 2

Both

Answer 3

\[\frac{ 1+\cos(y) }{ 1+\sec(y) }\]

Answer 4

simplified equals 1 + cos^2 (y) = sin^2 (y) right?

Answer 5

No, if it was \[1-\cos ^{2}y\] then it would be\[\sin ^{2}y\] but I think it is just \[\cos ^{2}y\]. Not 100% sure though

Answer 6

1 + cos^2 (y) = ??

Answer 7

It doesn't simplify beyond that, at least to my knowledge.

Answer 8

ok thanks for your time sir

Answer 9

No problem!
