When two lines intersect, the point of intersection will be a finite set of coordinates which can be obtained from the equation of either line. A sketch of the the functions will help you identify how man...

1. Set the equation equal to 0, which would be 5x^2 +x - 4 = 02) Split the equation into 2 brackets. To do this, one bracket will be (5x+ or - something) and the other will be (x + or - something), as ...

y_C=x³ - 7x + 3 ------> equation of curve.y_T=mx+c ----------------> equation of tangent, where m is the gradient of the graph and c is the value of the y-intercept (t...

We are looking for all the x values for which this equation holds. We know how to solve quadratic equations without the inequalities, and that is the first step here! So let's forget about the greater tha...

2x³ + 4x^3/2 - 5x + cGeneral rule for integration is increase the power by 1 then divide by the new powerAlways remember +C !!!!!!!
