Question

lim x tends to 0 sin ^2x/2x​

Answer 1

Answer:

The circumference of a circle is 2πr or πD if diameter is given.

The answer is 25.13 cm

Step-by-step explanation:

Now method 1:

C=2πr

So finding for radius in this equation=diameter/2

8/2=4 cm

So now 2 × 22/7 × 4

176/7=25.13 cm

OR

C=πD

22/7 × 8

176/7=25.13 cm

Answer 2

Answer:

Evaluate limit as x approaches 0 of (sin(2x))/( 2x). limx→0sin(2x)2x lim x → 0 ⁡ sin ( 2 x ) 2 x. Evaluate the limit of the numerator
