Another question for O Level Additional Mathematics (A-Math).
On the same diagram, sketch the graphs of
y=sin 3x & y=cos2x,
for x between 0 degree and 180 degree
Hence state the number of soutions to the equation
sin 3x=cos 2x
in the interval 0 degree less than or equals to x which is less then or equals to 180 degree

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 : )
