MATH 1550 : Practice Test #2
Document Summary
Practice test # 2, math 1550, summer 2011. In your test will be used the problems similar to your homeworks, webworks and class examples: find the derivatives of (1) f (x) = x9 arctan(4x) (2) g(x) = tan x x1 3. 2 (3) h(t) = sinh(3t5 1 t ) (4) f (x) = ln(arccos x3) 3: a lighthouse located on a small island 4 km away from the nearest point p on a straight shoreline and its light makes 2 revolutions per minute. How fast the beam of light moving alone the shoreline when it is 1 km from p? (round your answer to one decimal place. ) Any of your assigned problems for 3. 9 (from webassign) can be used here with di erent numbers. m k. 4: calculate a) d4f dt4 (cid:12) (cid:12) (cid:12) (cid:12)t=1. , f (t) = 6t9 2t5: find cos (3x), determine f (a) for a = 2, 0, 2, 4.
