Question

@phi Can you help me with a question please?

Sketch the graph of the tangent curve in the interval from 0 to 2 pi.

Answer 1

tan (-x) is -tan(x)
which means it is flipped

a "normal" tan
looks like
choice c (which means that is not the answer) because we want tan(-2x)

Answer 2

we want -tan(2x)
and 2x means we have 2 curves in the space of 1 "normal tan"
so twice as many, and flipped.

Answer 3

Would that make it choice B?

Answer 4

B is the right number, but it is not flipped

Answer 5

Ohh okay, so option D? Because it looks flipped.

Answer 6

yes , choice D

Answer 7

Thank you! I really appreciate it.
