BEHAVIORAL OBJECTIVES:
At the end of the lesson, the students should be able to understand and solve the following problems:
Write the negation of the following statements:
- All polygons are quadrilaterals
- It is a sunny day
- XYZ is an isosceles right angled triangle
- The figure is a cube
- X is not a prime number
- A ladder of length 4.5 m leans against a vertical wall making an angle of 500with the horizontal, if the bottom of a window is 4m above ground what is the distance between the top of the ladder and the bottom of the window? [Answer correct to the nearest m].
- From a horizontal distance of 8.5 km, a pilot observes that the angle of depression of the top and base of a control tower are 300and 330 respectively. Calculate, correct to 3 significant figures.
(a) The shortest distance between the pilot and the base of the control tower;
(b) The height of the control tower.
Use tables to find the values of the following.
- Cos 1300
- Tan (-1300)
- Sin 1110
- Sin (-3200)
The above are what is expected of a SS1 student to know and be able to understand with ease. The SS1 Mathematics third term lesson note here is aided with graphics so it makes it easier not just for the students but for the teachers too.
I have made the SS1 Mathematics third term lesson note available in a PDF format for free download without any extra cost as this would ease the passage of knowledge from teachers to students without hinderances. It is a my little way of giving back to the educational sector where I belong.
