Well Marlene I completed the problems...I think...and now I realize you already got help with it. Oh well.
I'm not positive I did it correctly b/c calc was 2 years ago, and I sadly realized I forgot how to do some of it, but my answers were:
1. 3[cos(sin2x)]^2 -sin(sin2x) + 2cos2x + 2
2. 5[xsin(2x) + tan^4(x^7)]^4 + 4sec^6(x^7) + 7x^6 + 2xcos2x + 2
Were those the answers you got?
"If there was a Mount Rushmore for Broadway scores, "West Side Story" would be front and center. It snaps, it crackles it pops! It surges with a roar, its energy and sheer life undiminished by the years" - NYPost reviewer Elisabeth Vincentelli
