Question

How do I know the domain of 50 tan theta - 50 theta?

Answer 1

The 50's don't matter. tan = sin/cos, which only has existence problems when cos = 0, so the domain is all real theta, except for when cos(theta) evaluates to zero, which is when \[\theta \neq \pm n \frac{\pi}{2}\] where n is an odd integer

Answer 2

typo: the not equal should be equal

Answer 3

Why is it only values of the first quadrant? I inferred that since you only mentioned pi/2 and not 3pi/2 as well

Answer 4

Also, tan of pi/2 is undefined because sin is 1 and cos is 0

Answer 5

its not only values in first quadrant
theta = +/- n pi/2 as uhhh as said
