1 ) use factoring to calculate this limit lim x -b x's - 63 ( your answer should be in terms of the variable " b" ) 2 ) Evaluate : lim 7 39 - x - 6 * - 3 7/ 52 - X - 1 3 ) Find the limit lim 7 4- - 00 3+ 10 Enter I fo o. - I for - o and ONE if the limit does not exist . 4) Evaluate : lim 3 ( sin x - cos x ) 3 cos 2x use cos ( 2 x ) = 2 cos " x - 1 = cosix - sin 2 x 5 ) Evaluate the limit lim tan ax X - O Sin 2* 6 ) Find the limit . Jim 1 - cos ( 3h ) ho cos 2 ( Gh ) - 1 Evaluate the limit lim x sin 5 ) X 70 8 ) use the Squeeze Theorem to evaluate the following limit . Enter I for an - I for - 0 and DNE if the limit does not exist . Sinx lim X - 00 X
