Document Summary

Hw 1 #1) (c) you see a bear cub in a tree on campus. Your distance from the tree is 100 ft. The angle between the ground and a straight line from your foot to the bear cub is /6 radians. How high up is the bear cub? (similar to written hw 1 #7a) If the opposite side has length 1 and the adjacent side has length 10, then the hypotenuse has length 101. 101 (b) cot x csc x = 4 cos x cos x sin2 x. Then cos x = 0 x = . 6 (c) let h be the height of the tree. 3 ft : core section: limits (30 points) Evaluate the following limits or explain why they don"t exist. Justify all answers. (a) lim x 0 (b) lim t 4 x cos x. |t 4| sin2 x (c) lim x x.
