A Day at the Parade Your first born child is marching in the street fair parade. To capture the event for posterity, you buy a camcorder especially constructed for your child. Perched on a platform with a tripod 20 ft. from Main Street, your fancy camera not only takes beautiful moving pictures, it records the distance d that your child is from the camera as you scan from left to right. (See the figure). We want to determine d as a function of θ for -ð/2 < θ < ð/2, where θ is negative when your child approaches from the left. 1. Explain why d is undefined for θ = ð/2 or -ð/2? Remember d is the distance your child is from the camera as your child marches down Main Steet. 2. By inspection (NO FORMULAS!), find d(0). 3. Develop an equation for d(θ) 4. Graph d vs. θ for -ð/2 < θ < ð/2. 20 ft. d θ camera
