How can you divide a fraction by a fraction using multiplication?
You find the reciprocal of the second fraction- flip it over. And then you multiply the two fractions.So (a/b) / (c/d) = (a/b) * (d/c)You find the reciprocal of the second fraction- flip it over. And then you multiply the two fractions.So (a/b) / (c/d) = (a/b) * (d/c)You find the reciprocal of the second fraction- flip it over.

How do you differentiate and find the tangent?
When you differentiate a function, you find the slope of the function. The slope is also known as the tangent. The slope of a line, given one point, and a second point relative to the first point, but with x different, is given as delta y over delta x. Differentiation is simply taking the limit of the slope, i.e. where delta x approaches zero.
How do you find the exact value of the gradient of the curve with equation y equals 1 divide by 4 minus x2 at the point where x equals 1 over 2?
You find the gradient of the curve using differentiation. The answer is 0.07111... (repeating).
How do you make a 80 degree angle using a ruler and a compass?
Draw a point, and a long straight line through it. Put the centre of the compass over the point, with north on the compass (or zero degrees) on the line. Then draw a second line out from the point at 80 degrees on the compass. You'll then have a 80 degree angle between the lines. It's usually a trick that teachers decide to do on their pupils. A compass is what you use to find north and a pair of compasses is used to draw circles.
