Can you give an example of a drawing of tangent graphs? For eg, 3tan2x + 1, what does each stand for and how do i go about drawing?
From the drawing, you see only 1 diagram instead of a few diagrams as what most people will have.
The secret is………… I drew my x and y axis LAST which is the reason why my diagram is so neat and it takes me less than 2 min to complete : )

Terms you must understand in Additional Maths (A-Maths) Trigo Graphs
1. Amplitude
2. Period
You must be able to sketch given any trigo eqn and vice versa, i’e given graphs, find the unknowns. Just like this 2006 o level a-math p1 qn.
Note the common mistake to avoid!
