3. Verification Steps

4. Theoretical Ananysis Equation for decay: Cosmicray e-lab program:
x-axis: t y-axis: dN/dt
Take the differential form:

5. Cosmicray e-lab result

6. Revision---Matlab
Input data into Excel then into Matlab

7. Revision---Matlab
Draw a histogram

8. Revision---Matlab Draw best-fitting line---change equations
Define y= , then , we take ln
on both sides:

9. Revision---Matlab
Y=-0.38*x+2.7

10. Calculation
= -0.38
= 2.63 μs
