@Mathematics

Answer 1

(tan(x))^2

Answer 2

oh wo zekarias thanks for the help

Answer 3

wow*

Answer 4

might you be able to help me out with another problem

Answer 5

off course

Answer 6

these are just the pythag identities
\[sin^2+cos^2=1\]
\[\frac{sin^2}{cos^2}+\frac{cos^2}{cos^2}=\frac{1}{cos^2}\]
\[tan^2+1=sec^2\]

Answer 7

If the point (2, -2) is on the terminal side of the angle θ, find each of sin(θ),cos(θ),tan(θ)

Answer 8

oh ok thanks amistre...hey i apologize about what happened last time

Answer 9

'sok, it happens :)

Answer 10

zekarias are you there

Answer 11

\[\sin \theta=-1/\sqrt{2}\]\[\cos \theta=1/\sqrt{2}\]\[\tan \theta=-1\]

Answer 12
