This grade 11 maths revision worksheet practices the two topics done in term 2 – functions and trigonometry. The questions ask to find x-intercepts, y-intercepts, asymptotes and turning points, as well drawing the graphs. There is a question on finding the general and specific solutions and one on proving identities. Download now: Worksheet 13: […]

This grade 8 worksheet begins with the basics of Pythagoras. It focuses on writing down the correct Pythagoras formula, substituting correctly into the formula, finding the longest side. It then moves on to finding any side of a right-angled triangle. Finally students are asked to prove that a triangle is right-angled by using the […]

This is really easy! If you have the x and y coordinates: For example: (3; 4) Type in 3 4 Your calculator screen will then look like this: r is your hypotenuse – which is 5 and your angle made with between the y-axis and the hypotenuse is 53o What if you have the angle and […]

To prove the CAST Diagram On your SHARP EL535 calculator press . Then type in . For X_Start: type in 90 and . For X_Step: type in 15 and . Look at the answers between -90 and 0 – are they all positive or all negative? They are all negative: therefore sin is negative between […]

The grade 11 mathematics trigonometry worksheet tests the sine, cosine and area rules learnt and determines whether students can apply it to two-dimensional (2D) questions. The questions are based on the South African Caps syllabus and there is a fully worked out memorandum. Download here: Worksheet 8: Trigonometry Worksheet 8 Memorandum: Trigonometry

Worksheet 7 starts with labeling the diagram of a triangle with the correct labels. It then moves onto to identifying the different trigonometry ratios before tackling solving the for a ratio given an angle (great calculator work). The worksheet then looks at determining the angle given the ratio. The worksheet then deals with reciprocals before […]
