Question

please answer

correct one ​

Answer 1

Answer:

1. 4

2. m/n

Step-by-step explanation:

we know limits of sinx/x and tanx/x is equals to 1.

In question 1,

separate the both,

Multiply and divide by 8x in Numerator and denominator in the term of Tan8x.

Also, Multiply and divide by 2x in Numerator and denominator in the term of Sin2x.

And watch the following step given in the image attached.

Remark one thing dear, that we multiplied and divided by 8x only in Numerator , to equalise the angle and the denominator. Since there is Tan 8x, therefore we have to divide by 8x to make it Tan8x/8x which is equals to 1 and since you have divided by 8x , you have to multiply also, that's the rule. Similarly, the whole thing is with Sin2x.

Guess you are now be clear about the question no 2.
