E-Math - Trigonometry - Trigonometric Ratio

Topic:Trigonometry

Trigonometric Ratios (i.e tangent, sine and cosine) can only be use
for right angle triangles. If it is NOT a right angle triangle, try 'cutting'
the triangles (see example above). If you find the diagram too
complicated or too messy from all your pencil marking, try drawing
out the portion of the diagram that you are solving.

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.
