for this type of question, integral by parts should be used . This involves using the formula for intregation by parts: lets first break apart the x and e 10x into two parts - "u" and "v"...

Step 1: Add a cumulative frequency column to the table Step2: Use the formula n/2 (where n is the final total in the cumulative frequency column) to find the class the median, Q 2 , is in. Let n/2= a, so tha...

If you are given a simple quadratic equation, for example x 2 +6x+8=0, then in order to factorise this you must find two numbers that add together to make the coefficient of x in the equation (in this case t...

Question: Line A has a gradient of 4 and passes through point (5,6). Line B passes through points C (0,5) and D (2,0). Find the coordinates of the point where the two lines intersection. Solution: First of a...
