Question

solve for x: tan^2(x)=10,000?

Answer 1

tan is squared

Answer 2

\(tan^2(x)=10000\)

Answer 3

yea like that

Answer 4

Well any ideas?

Answer 5

no

Answer 6

Well if I tell you a^2=100 then you would say a=10 maybe?

Answer 7

so youre saying a =tan?

Answer 8

No, I'm making a separate example to give you a hint so you can figure out what tanx is. tanx is not equal to a.

Answer 9

oh okay (tanx)^2=10,000=> tanx=100. im stuck after that

Answer 10

Are you expected to give an exact answer?

Answer 11

yes for x

Answer 12

Hint: Inverse

Answer 13

tan^-1 (100) ? like that

Answer 14

Yes
