Hiya! After a quick recap of algebra to start off the year, now we shall move on to vectors - one of the beloved topics. From dot product, cross product, equations of lines and planes to simultaneous equations, this test contains quite a lot of questions for students at various levels of attainment. Enjoy! AAHL: AAHL MS: Andrew  

Hiya! Lines and planes can be complex, can't they? On today's test we'll start with a standard on basics of vectors and the dot/cross products, equations of lines and planes and simultaneous equations. Obviously, HK is making an appearance here as the exams have  really good  simultaneous equations questions.  The actual test isn't gonna be this easy lmao Standard 2 is a time crunch.  Budget your time accordingly - if you're after that 7, you gotta speed up at the other standards.  If you're looking for more personalised support, don't hesitate to reach out and complete the form !

Hiya! Here's the unit test on vectors, to complete series Unit Test v2.3. The test has three standards as per usual - introduction to vectors, equations of lines and planes, and problems with lines and planes. A good old tip when dealing with any vectors question: please sketch it out! The answer will pop out readily in most cases.

Hey there kiddos! It's been a year since I last posted anything on vectors. Happy to report that it will be changed today!   The test consists of three standards - basics of vectors and vectors products, equations of lines and planes, and problems involving distances and angles. Go ahead and find the latest set of unit tests below. This set is, hopefully, still difficult but manageable for many of you. AAHL Vectors: Vectors MS: May the odds be ever in your favour.

Hey there kiddos!   N23s, good job! Enjoy your break before uni starts!! M24s, be ready. Your school may have mocks around this time or early next year, this is the time to make a difference!   I just realised I have a couple flashy torture devices unit tests in my vault ready to go, and today let’s do a bit of vectors. QP: MS:      

Second collection of unit tests: trigonometry and vectors. Occasionally featuring questions from endless inspirational sources. Answers included. Unit Tests Version 1 Part 1: Trig relationships (AASL/AAHL)  The trio (sine/cosine rules and area of a triangle), sectors and the unit circle. Part 1: Trig relationships (AISL/AIHL)  Same as above, just slightly modified. Part 2: Trig identities and equations (AASL/AAHL)  Trig identities and equations, including Pythagorean identities and compound angle identities for AAHL. Vectors (AAHL) : lines and planes in 3D. Version 2 Trig relationships (AASL/AAHL) Sine rule, cosine rule, area of a triangle and sectors. Trig functions (AASL/AAHL)  The start of triangles become circles, v2. Trig identities (AASL/AAHL)  Second part of triangles become circles. And graphs. Vectors : lines and planes in 3D.   Version 2.2 Trig relationships v2.2 Sine rule, cosine rule and area of a triangle, and other things. Trig functions v...

Hello AAHL kiddos. Y'all may have noticed an omission from all the tests I've posted so far. Yup, it's vectors, the topic that many students either adore its beauty or dread its abstraction. This test covers the entire topic of vectors, including equations of lines and planes.  Be nice to the question paper - it's not its fault that this test is so bloody difficult. Best of luck. Relax. Breathe. Stay calm. You got this.  Question paper Answers Source: AdventurousAndrew#7499 2021
