Let's prove that the area under a standard normal curve (a bell-shaped curve with mean of 0 and standard deviation of 1) is equal to one.

I searched for this thanks. Also i have a question: in our math lecture my teacher explain this curve for e^-x^2. Is there a difference?

Sir i m in class 12th please tell me i dont understand how u multiply 2 multiple and my sir told that e^x^2 is out of class 12 syllabus ....please tell me....

Hey, nice video ! What if i say :
The normal distribution is a probability distribution, the biggest value will be 1 (Since P<1 or P = 1). So, if we want to get ex.
the area of μ-3σ or μ+3σ we will get : integral 1/σradical2π * e^ (x-μ)^2/ 2σ^2 = P ( μ-3σ <= z <= μ+3σ) = 99, 7%. So by this :
integral 1/σradical2π * e^ (x-μ)^2/ 2σ^2 = P ( -oo <= z <= +oo) = 1
is it correct ?
