“OR” TRUTH TABLE:
“AND” TRUTH TABLE
“NOT” TRUTH TABLE
“IMPLIES” TRUTH TABLE
Firstly you have to know what (a+b+c)(d+e+f) is. You can expand this expression using a rectangle:
So you know that:
Next you’d have to multiply (a+b+c)(d+e+f) by (g+h+i) using another rectangle:
And from here you’d figure out that:
Find out how to come up with the Trapezium Rule formula from scratch.
1) Derive the formula for the area of trapeziums:
2) Use the area of trapeziums formula to come up with the Trapezium Rule formula:
