SOLUTION: Will sin(x) ever equal cos(x)? I do not need solutions. Also, does sin(x) = cos(x - {{{pi}}}/2)? Explain.

Question 49322: Will sin(x) ever equal cos(x)? I do not need solutions. Also, does sin(x) = cos(x - /2)? Explain.

Yes, sin(x) will equal cos(x) eventually:

Does sin(x) = cos(x - /2) .... Yes
Remember: sin(x - 1) shifts horizontally -c units
sin(/2) = 0
cos(0) = 0
So, sine is /2 to the right of cosine.
Cos(x - /2):

Sin(x):
