Question

Is saying both of these the same thing?

Answer 1

\[\tan^2 x\] and \[\tan(x^2)\]

Answer 2

no, those are two completely different things

the first one is really saying ( tan(x) )^2

Answer 3

Ah. Okay. So to type in the first form into my calculator, I do (tan(x))^2, correct?

Answer 4

correct

Answer 5

Thanks!

Answer 6

you're welcome

Answer 7

No. tan^2(x) is (tan x)^2. tan (x^2) is completely different.

For example, take x = 5 radians. tan^2(5) = 11.43, while tan (5^2) = tan(25) = -0.1335.

Answer 8

All right, thanks again, guys! ^.^
