Find the line equation that intercept with x- and y- axis at points A(-4, 0) and B(0, 4), respectively. Step 1. m = (4-0)/(0-(-4))= 1 Step 2. Pick point A. Key in its x and y coordinates to find constant C. y = mx + C y = x + C -...
Step 2– as we can see in the snapshot above, the calculator needs some information to be provided as input for the purpose of calculations. These are the radius of the circle and the angle in radians. Therefore, in the second step, we will first enter the radius of the circle. Let ...
How to use the circumference calculator to find the circumference of a circle? What is a circle? A circle is the set of all those points in a plane whose distance from the fixed point remains constant. The fixed point is called thecentreof the circle and the constant distance is known as...
If you know the circle’s diameter, you canfind the radiusby dividing the diameter in half. A = π(d/2)2 d = diameter How to Find Area of an Ellipse An ellipse, or oval, is a shape where the sum of the distances from two fixed points, called the foci, is constant. An ellipse...
One handy thing about the sum and difference rule for finding the limit of functions is that you can use them in any combination, and you can also use them with the other laws for limits: the product law, the quotient law, and the constant multiple law. That allows us to simplify expre...

and they knew their grades on their assignments were more for things like how they applied the tactic we were learning. But last class they walked in and I gave them a Part 3 exam (the non-calculator part) and told them it would be graded – but there would be a plot twist. For ri...
