6. In the diagram below, a 2 m long stick is swung up in an arc so that at its highest point, it makes a 550 angle with the original vertical direction. Find the height through which the bottom of the stick has swung up. 7. d/dx (sin 0) =? 8. sin 0 de =? 9 . d/dx( 2x2 + 3x - 10) =? 10. S (2t + 612 - 3) dt =
