Question

What are the period and phase shift for f(x) = tan(2x + pi)?

Answer 1

If f(x) = tan(Ax + B), then:
Period = pi / A
Phase shift = -B/A

Answer 2

-pi/2?

Answer 3

That is the phase shift.

Answer 4

and pi/2?

Answer 5

Yes, Period = pi/2

Answer 6

and can yu help me with What are the sine, cosine, and tangent of 5 pi over 4 radians?

Answer 7

you are the best btw

Answer 8

sin Θ = square root 2 over 2; cos Θ = negative square root 2 over 2; tan Θ = −1

sin Θ = negative square root 2 over 2; cos Θ = negative square root 2 over 2; tan Θ = 1

sin Θ = square root 2 over 2; cos Θ = negative square root 2 over 2; tan Θ = 1

sin Θ = negative square root 2 over 2; cos Θ = square root 2 over 2; tan Θ = −1

Answer 10

the 3rd

Answer 11

Correct. What are the signs of sine, cosine and tangent in the 3rd quadrant?

Answer 12

-2√2,-2√2, 1? idrk tangent im pretty sure thats it

Answer 13

Yes.

Answer 14

yay thnk you! i have like 7 more can you help real quick please :*

Answer 15

tan = sin / cos. So if you know sine and cosine as you listed above you can easily find tan by dividing: sin / cos.

Just for variety let someone else help you while I help someone else. that way you will get a different perspective on doing the problems and I will have some variety answering too.

Answer 16

ok :( no one else is helping me though
