Question

Consider the function

\(f(x) = \tan(x) := \tan(x) := \frac{sin(x)}{cos(x)}\)

a) Determine the maximal Interval of deinfintion \(I\) and \(0\)

Answer 1

you want the maximum interval ,that contains zero, on which f(x) can be defined?

Answer 2

yes..

Answer 3

find where \(\cos(x)=0\)

Answer 4

ok..

Answer 5

bu how..

Answer 6

\(\cos(x)\) and \(\sin(x)\) are continuous functions so the only place \(f(x)\) can't be defined is when the denominator is equal to zero

Answer 7

refer to the unit circle

Answer 8

ok..

Answer 9

hm @Zarkon i need full solution, if i do it by myself i will get low points which could led me to be unable to participate at final exams :)
