1. Determine the following limits:: (i) lim sin (11x) cos (3 - 3x (ii) lim (iii) lim coot sin (3VT) (iv) lim 7 sin(3.x) x-+0 tan(2x) 2. If h is a function such that 4x - 9 0. Determine lim h(x) 3. Use the Squeeze Theorem to determine the following limits: (i) lim ( cos 2-+0 (ii) lim (2 + sin (x)) -+00 r + 100 4. Sketch the function f such that if r 1 Discuss (i) left and right continuity and (ii) continuity or discontinuity of the function f at r = -1 and r = 1
