The three basic trigonometric functions have periods as demonstrated below: ï· Sine function -> period is 2ï°radians or 360ï°. ï· Cosine function -> period is 2ï°radians or 360ï°. ï· Tangent function -> period is ï°radians or 180ï°. The basic graphs of these 3 trigonometric functions are: The length of one complete cycle of a trigonometric function is called the Period. Typically we use x=0 as the starting point for the graph. When the length of the period. is not the default, the functions will be written in the format similar to: f t ktï¨ï©ï½sinï¨ï©, g x kxï¨ï©ï½cosï¨ï©, or h kï¨ï±ï©ï½tanï¨ï±ï©.
6 Dec 2012. p.s. some people find prozac to be sedating, it helps with panic or anxiety, while others feel it does nothing for anxiety. It usually takes around 4 to 6 weeks to begin working, on someone who is NOT on an antidepressant already.
Re: Prozac/tired! Yes. i take prozac (fluoxetine). it did make me very tired for the first 6-8 weeks. then all of a sudden i had more energy then i knew what to do with. i take mine in the morning. just cause that is when i remember to take it. have been on 20 mg of prozac for about a month now. I am extremely tired all the time. I have to take daily naps and sometimes 2! I don't have any motivation or energy to do anything. However my mood is much better.
