  1. Upward Bound Math and Science PRECALCULUS

  2. Slope of Line • The Slope of a Line is give by the formula • Find the slope of the line (-1,4) and (2,-2)

  3. Positive Slopes go uphill

  4. Negative slopes go downhill

  5. Equation of Line • The equation of line when one point on the line and slope is given by the formula y-y1=m(x-x1) Where (x1,y1) are the point and m is the slope

  6. Problem • Find the equation of the line passing through the point (4,-3) with slope of -3

  7. Distance between two points • The distance between two points on the coordinate plane is given by the formula

  8. Problem • Find the distance between ( -1,23) and (23,-1)

  9. Angles ( Radians)

  10. Angles ( Degrees)

  11. Unit Circle

  12. Trignometry

  13. Trigonometry identities

  14. Problem • Solve Cos2q+Cosq = 0 • Hint : Cos2q = 2Cos2q-1

  15. Problems • A ladder leans against a building.  The foot of the ladder is 6 feet from the building.  The ladder reaches a height of 14 feet on the building. • Find length of the ladder towards the nearest foot • Find the angle between the ladder and building

  16. Problems • From a point on the ground 25 feet from the foot of a tree, the angle of elevation of the top of the tree is 32º.  Find to the nearest foot, the height of the tree.

  17. Problems • The figure shown on the left is a trapezoid.  Using the information given, find the area of this trapezoid to the nearest square unit.

  18. Problems • In the figure on the left, ABCD is a rectangle whose perimeter is 30.   The length of BE is 12.  Find to the nearest degree, the measure of angle E. 

  19. Problems • Find x
