Differentiate the equation 4x^5 + 2x^3 - x + 2
When you differentiate you find the equation which lets you find the gradient of the equation at a specific point.To do so you multiply the power of the x by the respective coefficient, then that becomes the new coefficient, finally subtract 1 from the power.So (45)x^(5-1) + (23)x^(3-1) - (11)x^(1-1) + (20) = 20x^4 + 6x^2 -1

A ball is thrown from ground level at an angle of 30 degrees from the horizontal with a velocity of 20 m/s. It just clears a wall with a height of 5m, from this calculate the distances that the wall could be from the starting position.
At each point P of a curve for which x > 0 the tangent cuts the y-axis at T, and N is the foot of the perpendicular from P to the y-axis. If T is always 1 unit below N and the curve passes through the point (1,0), find the Cartesian equation of the curve.
