Sketch a graph of the function y=cos^-1x Part I: First, sketch at least two periods of the function y=cosx
on the graph below.
What are the domain and range of the function y=cosx
Restrict the domain of the functiony=cosx
so that it may be inverted. That is, select the portion of the graph ofcosx that is suitable for inverting. Mark that portion on your graph from Part I.

Alina fully simplifies this polynomial and then writes it in standard form. xy2 – 2x2y + 3y3 – 6x2y + 4xy2 if alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form? xy2 5xy2 –8x2y –2x2y
