| Topic: Trigonometry |
Use Pythagoras Theorem to find the value of the unknown side,
you will get a two answers a positive and a negative, however
you can only use one value. You should check the x-axis or
y-axis to determine if the value is positive or negative in that
particular trigonometry quadrant.
I created this Blog after my students told me that there is very little information about how to solve GCE O Level Math and Additional Math (A-Math) questions on the internet. Even if they manage to find, the solution were for very basic questions. I am a Full-time Math Tutor in Singapore. I tutor mainly in Northern Singapore (Woodlands, Chua Chu Kang, Bukit Panjang, Yishun and Sembawang). I also tutor in Johor Bahru.
