Question

Find the limit of the function by using direct substitution lim (2e^x sin x) x --> pi/2

Answer 1

just plug in pi/2 into the equation.

Answer 2

2e^(pi/2) * Sin(pi/2)

Answer 3

such a simple question simply put x=pi/2

Answer 4

what about e?

Answer 5

use a calculator, e is a constant.

Answer 6

about 2.71...

Answer 7

I got 349 and that isn't an option on my choices :(

Answer 8

Btw :
\[\Huge \frac{\pi}2=\frac{180}2=90\]

Answer 9

I have 0, 1, 2e^pi/2 and pi/2

Answer 10

is pi/2 the answer or should I use 90 to solve the equation?

Answer 11

because I used 3.14 as pi

Answer 12

(2e^x sin x) x = 2e^(pi/2)*Sin(pi/2)*(pi/2) = 2e^(pi/2)*(pi/2)

Answer 13

@Eyad

Answer 14

= pi * e^(pi/2) that's the final answer

Answer 15

thank you!!
