2. Lim x0x 1 sin x

Find lim(2 – x)tan(rx/2)

(sinx -) lim, (3sin²x -sinx +1) TE +X, 2

Vx+2-3 (а) lim x→7 х — 7 4x? + 3х-10 (b) lim 2 х-> —2 х*+ 8х +12 sin xcos x (c) lim x→ 0 x(х + 6)

x-sinx (1) lim x2 (H) 은( e2x.cos x) (iii) Stan 2x dx (iv) (sech 2x) dx (v) S(sin x +–) dx 5x (vi) 을 (x+3x)5

The value of a and b so that x(1 + a cos x)- b sin x lim =1 are 3 3 5 (b) 2 2 (a) (e) - 3 (c) 3 (d) 2' 2 1/2 (4)
