find the 2 points of intersection of the line y=1/2 and sin(x). these points are pi/6 and 5pi/6

these become lower and upper limits respectively, then integrate sin(x).

To find intersection points, let , then (taking into consideration the domain).

Drawing the graph, we know that the area is given by:



Solve and you have the area. :)

okay what i typed into the calculator is: and that gives me a general solution

The | sign should be put in AFTER the brackets:

i type this exactly in my CAS but get incorrect number of arguments :( i've been tryna figure out how to solve bounds with integrals for a while but it wont work

-edit- nvm just found out :D space b/w dx and =

please be more specific, what is dilated from what?

Anyway I assume you mean the original function is then it gets dilated to and then translated.

In that case the dilation (in bold) is a factor of from the X-axis, why? If then
