Discrete Math: Prove that there can be no perfect square between 25 and 36, i.e. there is no integer n so that 25 < n2 < 36. Prove this by directly proving the negation. Your proof must only use integers, inequalities and elementary logic. You may use that inequalities are prsered by adding a number on both sides, or by multiplying both sides by a positive number. You cannot use the square root function. Do not write a proof by...
Find the points of horizontal tangency to the polar curve. r = a sin ose<, a > 0 (r, 0) = (smaller r value) (r, 0) = (larger r value) Find the points of vertical tangency to the polar curve. (r, ) = (smaller e value) (r. 2) = (larger e value)
