Question 1009225
Using these similarities and differences, how would you transform 
f(x) = 2 sin(2x - π) + 3 into a cosine function in the form
f(x) = a cos(bx - c) + d?
--------
Note:: sin(x) = cos((pi/2)-x)
So, sin(2x-pi) = cos((pi/2)-(x-(pi/2)) = cos(pi-x)

-----
Ans:: 2cos(pi-x)+3 OR 2cos(-x-(-pi)) + 3

------------
