Answer:
<h2>The value of

</h2>
Step-by-step explanation:
given slope= 
the the points
and (2, y) 
now, the slope of
and (2, y) are equal to 
<h2>so

</h2>
cross multiplication, we get
<h2>

</h2><h2>
therefore the value of 
</h2>
Answer with Step-by-step explanation:
We are given that 
We have to prove that why the limit x approaches 0(csc(x)-cot(x)) involves an indeterminate form and prove that the limit equals to 0.

Because
and


We know that cos 0=1 and sin 0=0
Substitute the values then we get

We know that
is indeterminate form
Hence, the limit x approaches 0(csc(x)-cot(x)) involves an indeterminate form.
L'hospital rule:Apply this rule and differentiate numerator and denominator separately when after applying
we get indeterminate form
Now,using L' hospital rule

because 
Now, we get



Hence,
Answer:
No,yes,yes,no,yes
Step-by-step explanation:
I think that the answer is 15*10^5
