Question

What are the formulas to find the period of a sin, cos, sec, or csc function?

Answer 1

why not do an Internet search for "period of the sine function?" I did, and obtained the following:

https://www.google.com/search?q=period+of+the+sine+function&rlz=1C1CHFX_enUS461US461&oq=period+of+the+sine+function&aqs=chrome..69i57j0l5.5776j0j7&sourceid=chrome&es_sm=122&ie=UTF-8

Answer 2

yeah i had done that too, but i wasn't able to find an exact formula for all of those

Answer 3

@mathmale I know that period=2pi/k is a basic formula for finding the period, but is that the same formula for all of the trig functions that i listed or just for sine? because i need to find all of them

Answer 4

Yes, the formula for the period is the same for the sine and cosine functions.
Note: the secant is the reciprocal of the cosine function, and thus ALSO has the period 2Pi/k.
Likewise, the cosecant is the recip. of the sine function, and thus ALSO has the period 2Pi/k.

Answer 5

Ohhhh that makes sense now, thank you!:)
