Limit question: lim x-->pi ((e^sinx)-1)/(x-pi)

aleksandr82 [10.1K]

$\displaystyle\lim_{x\to\pi}\dfrac{e^{\sin x}-1}{x-\pi}$

Notice that if $f(x)=e^{\sin x}$ , then $f(\pi)=e^{\sin\pi}=e^0=1$ . Recall the definition of the derivative of a function $f(x)$ at a point $x=c$ :

$f'(c):=\displaystyle\lim_{x\to c}\frac{f(x)-f(c)}{x-c}$

So the value of this limit is exactly the value of the derivative of $f(x)=e^{\sin x}$ at $x=\pi$ .

You have

$f'(x)=\cos x\,e^{\sin x}\implies f'(\pi)=\cos\pi\,e^{\sin\pi}=-1$

Alex787 [66]

Thank you for posting your question here at brainly. I hope the answer will help. Belowis the solution:

Let X be a random variable for the Celtics score. Then you want

P(X > 101.7) 
 1 - P(X < 101.7) 
 = 1 - P((X - μ)/σ < (101.7 - 99.2)/10.5)) 
 = 1 - N_Z(0.2381)
