Question

The intersecting point of the line x = 4 and = - 4 is...​

Answer 1

Answer:

The intersecting point of the line x = 4 will be ( o,4)

and

The intersecting point of the line x = - 4 will be (0,-4)

Answer 2

Answer is 3

We all know that
limit (sin u)/u =1;
u-> 0

Now in over case just divide and multiply by 3.
.
. . Here we go

Lim (sin 3x)/x
x->0


Lim 3(sin 3x)/3x
x->0


Let 3x to be “u”

Than


Lim 3(sin u)/u
x->0

Which is 3*1 = 1

Hope this will help you dear
