6) A windmill is 40 meters tall at it's centre of axis of rotation and has three blades each measuring\" 1 0m. a) Determine both a sine and cosine function to represent the motion of the blade. Assume the blade's motion starts at the bottom and moves counter clockwise. Show your work on how you got your answers. [5] a) Graph the height of the tip of a blade that starts at_ the bottom of the windmilliand rotates around the counterclockwise. Graph at least 2 rotations. Choose an appropnate scale and label your graph clearly
