hi

anonymous · Answer

Key features would be x-intercepts, y-intercepts, amplitude, and period

thats it? is that the answer? :O

i am not a very good singer

So like cos x y-int is at 0,1 and it has a x-intercept at pi/2 and 3pi/2 so the period would be 2pi for  cos x and both cos x and sin x have the same amplitude and period
