=e^(-i)∫e^i*e^(ix? )dx
=e^(-i)∫e^(-x? )dx
=√πe^(-i)
=√π(cos 1-isin 1
Then write (p'-p), not counting, just write this answer. Remember to add the previous (1/ root number 2π times h) to form the whole function, otherwise it is wrong. (1/ root number 2π times h) is used to calculate angular momentum, and you can write the answer directly by adding the corresponding function in front.
Extended data
For example:
Calculate the integral of ∫ (x 2) exp (-x 2) dx:
f(x)=[ 1/√(2pi)]*exp(-x^2)
EX=0DX= 1
Ex 2 = dx+(ex) 2 =1= ∫ x2f (x) dx from negative infinity to positive infinity.
therefore
∫x^2*[ 1/√(2pi)]*exp(-x^2)dx= 1
∫(x^2)exp(-x^2)dx=√(2pi)
The ultimate goal of mathematics teaching is to enable students to form a mathematical literacy and mathematical ability. Mathematics handwritten newspaper is an
