Question

pls help me with the question from math class 11 of chapter limits and derivatives​

Answer 1

Answer:

(a+1)/b

Step-by-step explanation:

lim (ax+ x cos x)/b sin x

x-->0

(dividing num. and dem. by x)

lim (ax + x cos x)/x / b sin x/x

x-->0

lim (a + cos x)/ b sin x/x

x-->0

(we know lim sin x/x=1)

x-->0

so,

(a+1)/b is the answer
